The first player to arrive there gets the comfort of 0.\n\nWhat is the maximum total comfort the N players can get by optimally choosing the order of arrivals and the positions in the circle to cut into?\n\nConstraints\n\nAll values in input are integers.\n\n2 \\leq N \\leq 2 \\times 10^5\n\n1 \\leq A_i \\leq 10^9\n\nInput\n\nInput is given from Standard Input in the following format:\n\nN\nA_1 A_2 \\dots A_N\n\nOutput\n\nPrint the maximum total comfort the N players can get.\n\nSample Input 1\n\n4\n2 2 1 3\n\nSample Output 1\n\n7\n\nBy arriving at the place in the order Player 4, 2, 1, 3, and cutting into the circle as shown in the figure, they can get the total comfort of 7.\n\nThey cannot get the total comfort greater than 7, so the answer is 7.\n\nSample Input 2\n\n7\n1 1 1 1 1 1 1\n\nSample Output 2\n\n6", "split": "validation", "target_descriptions": {"code_size_bytes": "Submitted source-code file size, in bytes.", "cpu_time_ms": "Execution CPU time reported by official Project CodeNet metadata, in milliseconds.", "memory_kb": "Peak memory usage reported by official Project CodeNet metadata, in kilobytes."}, "targets": {"code_size_bytes": 2115, "cpu_time_ms": 117, "memory_kb": 7244}, "variant": "low_resource"} {"dataset": "codeNet", "domain": "code_generation", "example_id": "codeNet:Fortran:s254917112", "group_id": "codeNet:p02616", "input_text": "program abc5\n implicit none\n integer::N=0,K=0,s=0,i,ishota,ishotb,p=0,q=0\n integer,allocatable::a(:)\n read(*,*)N,K\n allocate(a(N))\n read(*,*)(a(i),i=1,N)\n do ishota=1,N\n do ishotb=1,N-1\n if(a(ishotb)>a(ishotb+1))then\n p=a(ishotb)\n q=a(ishotb+1)\n a(ishotb)=q\n a(ishotb+1)=p\n end if\n end do\n end do\n s=product(a(N-K+1:N))\n print'(i0)',mod(s,(10**9+7))\n deallocate(a)\nend program abc5", "language": "Fortran", "metadata": {"date": 1594162804, "filename_ext": "f", "original_language": "Fortran (GNU Fortran 9.2.1)", "problem_description_relpath": "problem_descriptions/p02616.html", "problem_id": "p02616", "resource_group": "low_resource", "sample_input_relpath": "derived/input_output/data/p02616/input.txt", "sample_output_relpath": "derived/input_output/data/p02616/output.txt", "source_dataset": "Project CodeNet", "source_relpath": "data/p02616/Fortran/s254917112.f", "split_policy": "Global OOD problem IDs are disjoint from train, validation, and in-distribution test problem IDs.", "status": "Wrong Answer", "submission_id": "s254917112", "user_id": "u897889420"}, "prompt_components": {"gold_output": "12\n", "input_to_evaluate": "program abc5\n implicit none\n integer::N=0,K=0,s=0,i,ishota,ishotb,p=0,q=0\n integer,allocatable::a(:)\n read(*,*)N,K\n allocate(a(N))\n read(*,*)(a(i),i=1,N)\n do ishota=1,N\n do ishotb=1,N-1\n if(a(ishotb)>a(ishotb+1))then\n p=a(ishotb)\n q=a(ishotb+1)\n a(ishotb)=q\n a(ishotb+1)=p\n end if\n end do\n end do\n s=product(a(N-K+1:N))\n print'(i0)',mod(s,(10**9+7))\n deallocate(a)\nend program abc5", "problem_context": "Score : 500 points\n\nProblem Statement\n\nGiven are N integers A_1,\\ldots,A_N.\n\nWe will choose exactly K of these elements.

(a dot).\nOtherwise, it must contain a lowercase English letter.\nSquares covered by the same domino piece must contain the same letter.\nIf two squares have a common side but belong to different pieces, they must contain different letters.\n\nSample Input 1\n\n6\n\nSample Output 1\n\naabb..\nb..zz.\nba....\n.a..aa\n..a..b\n..a..b\n\nThe quality of every row and every column is 2.\n\nSample Input 2\n\n2\n\nSample Output 2\n\n-1", "split": "validation", "target_descriptions": {"code_size_bytes": "Submitted source-code file size, in bytes.", "cpu_time_ms": "Execution CPU time reported by official Project CodeNet metadata, in milliseconds.", "memory_kb": "Peak memory usage reported by official Project CodeNet metadata, in kilobytes."}, "targets": {"code_size_bytes": 710, "cpu_time_ms": 228, "memory_kb": 1152}, "variant": "low_resource"} {"dataset": "codeNet", "domain": "code_generation", "example_id": "codeNet:Fortran:s387503980", "group_id": "codeNet:p02830", "input_text": "program strings_with_the_same_length\n implicit none\n integer :: n, i\n character(100) :: s, t\n read(*,*) n\n read(*,*) s, t\n do i = 1, n\n write(*,'(a)',advance='no') s(i:i)//t(i:i)\n end do\n write(*,*)\nend program strings_with_the_same_length", "language": "Fortran", "metadata": {"date": 1577066615, "filename_ext": "f", "original_language": "Fortran (gfortran v4.8.4)", "problem_description_relpath": "problem_descriptions/p02830.html", "problem_id": "p02830", "resource_group": "low_resource", "sample_input_relpath": "derived/input_output/data/p02830/input.txt", "sample_output_relpath": "derived/input_output/data/p02830/output.txt", "source_dataset": "Project CodeNet", "source_relpath": "data/p02830/Fortran/s387503980.f", "split_policy": "Global OOD problem IDs are disjoint from train, validation, and in-distribution test problem IDs.", "status": "Accepted", "submission_id": "s387503980", "user_id": "u506403362"}, "prompt_components": {"gold_output": "icpc\n", "input_to_evaluate": "program strings_with_the_same_length\n implicit none\n integer :: n, i\n character(100) :: s, t\n read(*,*) n\n read(*,*) s, t\n do i = 1, n\n write(*,'(a)',advance='no') s(i:i)//t(i:i)\n end do\n write(*,*)\nend program strings_with_the_same_length", "problem_context": "Score : 200 points\n\nProblem Statement\n\nGiven are strings s and t of length N each, both consisting of lowercase English letters.\n\nLet us form a new string by alternating the characters of S and the characters of T, as follows: the first character of S, the first character of T, the second character of S, the second character of T, ..., the N-th character of S, the N-th character of T.

Statement\n\nKenkoooo is planning a trip in Republic of Snuke.\nIn this country, there are n cities and m trains running.\nThe cities are numbered 1 through n, and the i-th train connects City u_i and v_i bidirectionally.\nAny city can be reached from any city by changing trains.\n\nTwo currencies are used in the country: yen and snuuk.\nAny train fare can be paid by both yen and snuuk.\nThe fare of the i-th train is a_i yen if paid in yen, and b_i snuuk if paid in snuuk.\n\nIn a city with a money exchange office, you can change 1 yen into 1 snuuk.\nHowever, when you do a money exchange, you have to change all your yen into snuuk.\nThat is, if Kenkoooo does a money exchange when he has X yen, he will then have X snuuk.\nCurrently, there is a money exchange office in every city, but the office in City i will shut down in i years and can never be used in and after that year.\n\nKenkoooo is planning to depart City s with 10^{15} yen in his pocket and head for City t, and change his yen into snuuk in some city while traveling.\nIt is acceptable to do the exchange in City s or City t.\n\nKenkoooo would like to have as much snuuk as possible when he reaches City t by making the optimal choices for the route to travel and the city to do the exchange.\nFor each i=0,...,n-1, find the maximum amount of snuuk that Kenkoooo has when he reaches City t if he goes on a trip from City s to City t after i years.\nYou can assume that the trip finishes within the year.\n\nConstraints\n\n2 \\leq n \\leq 10^5\n\n1 \\leq m \\leq 10^5\n\n1 \\leq s,t \\leq n\n\ns \\neq t\n\n1 \\leq u_i < v_i

connects City u_i and v_i bidirectionally.\nAny city can be reached from any city by changing trains.\n\nTwo currencies are used in the country: yen and snuuk.\nAny train fare can be paid by both yen and snuuk.\nThe fare of the i-th train is a_i yen if paid in yen, and b_i snuuk if paid in snuuk.\n\nIn a city with a money exchange office, you can change 1 yen into 1 snuuk.\nHowever, when you do a money exchange, you have to change all your yen into snuuk.\nThat is, if Kenkoooo does a money exchange when he has X yen, he will then have X snuuk.\nCurrently, there is a money exchange office in every city, but the office in City i will shut down in i years and can never be used in and after that year.\n\nKenkoooo is planning to depart City s with 10^{15} yen in his pocket and head for City t, and change his yen into snuuk in some city while traveling.\nIt is acceptable to do the exchange in City s or City t.\n\nKenkoooo would like to have as much snuuk as possible when he reaches City t by making the optimal choices for the route to travel and the city to do the exchange.\nFor each i=0,...,n-1, find the maximum amount of snuuk that Kenkoooo has when he reaches City t if he goes on a trip from City s to City t after i years.\nYou can assume that the trip finishes within the year.\n\nConstraints\n\n2 \\leq n \\leq 10^5\n\n1 \\leq m \\leq 10^5\n\n1 \\leq s,t \\leq n\n\ns \\neq

are integers.\n\nInput\n\nInput is given from Standard Input in the following format:\n\nn m s t\nu_1 v_1 a_1 b_1\n:\nu_m v_m a_m b_m\n\nOutput\n\nPrint n lines.\nIn the i-th line, print the maximum

2.\n\nNote that City 1 can still be visited even after the exchange office is closed.\nAlso note that, if it was allowed to keep 1 yen when do the exchange in City 2 and change the remaining yen into snuuk, we could reach City 3 with 999999999999998 snuuk, but this is NOT allowed.\n\nAfter 2 years, it is optimal to do the exchange in City 3.\n\nAfter 3 years, it is optimal to do the exchange in City 4.\nNote that the same train can be used multiple times.\n\nSample Input 2\n\n8 12 3 8\n2 8 685087149 857180777\n6 7 298270585 209942236\n2 4 346080035 234079976\n2 5 131857300 22507157\n4 8

Under this condition, she will hand the minimum amount of money.\n\nFind the amount of money that she will hand to the cashier.\n\nConstraints\n\n1 ≦ N < 10000\n\n1 ≦ K < 10\n\n0 ≦ D_1 < D_2 < … < D_K≦9\n\n\\{D_1,D_2,...,D_K\\} ≠ \\{1,2,3,4,5,6,7,8,9\\}\n\nInput\n\nThe input is given from Standard Input in the following format:\n\nN K\nD_1 D_2 … D_K\n\nOutput\n\nPrint the amount of money that Iroha will hand to the cashier.\n\nSample Input 1\n\n1000 8\n1 3 4 5 6 7 8 9\n\nSample Output 1\n\n2000\n\nShe dislikes all digits except 0 and 2.\n\nThe smallest integer equal to or greater than N=1000 whose decimal notation contains only 0 and 2, is 2000.\n\nSample Input 2\n\n9999 1\n0\n\nSample Output 2\n\n9999", "split": "validation", "target_descriptions": {"code_size_bytes": "Submitted source-code file size, in bytes.", "cpu_time_ms": "Execution CPU time reported by official Project CodeNet metadata, in milliseconds.", "memory_kb": "Peak memory usage reported by official Project CodeNet metadata, in kilobytes."}, "targets": {"code_size_bytes": 738, "cpu_time_ms": 5, "memory_kb": 256}, "variant": "low_resource"} {"dataset": "codeNet", "domain": "code_generation", "example_id": "codeNet:Fortran:s308444173", "group_id": "codeNet:p04046", "input_text": "program main\n implicit none\n integer(8),parameter::M=1000000007\n integer(8) h,w,a,b,i,asize\n integer(8),allocatable::fact(:),invf(:)\n integer(16)::i16=0\n\n read*,h,w,a,b\n asize=h+w\n allocate(fact(asize+1),invf(asize+1))\n\n fact(1:2)=1\n do i=1,asize\n fact(i+1)=mod(fact(i)*i,M)\n enddo\n invf(asize+1)=powmod(fact(asize+1))\n do i=asize,1,-1\n invf(i)=mod(invf(i+1)*i,M)\n enddo\n \n print*,mod(dot_product(&\n i16+mod(fact(h-a+b:h-a+w-1)*invf(b+1:w),M),mod(fact(w-b+a-1:a:-1)*invf(w-b:1:-1),M))*mod(invf(h-a)*invf(a),M),M)\n\n !end program main\ncontains\n function powmod(t) result(r)\n integer(8),intent(in)::t\n integer(8)x,i,r\n i=M-2\n x=t\n r=1\n do\n if ( i .eq. 0 ) exit\n if ( iand(i,1).eq.1 )then\n r=mod(r*x,M)\n endif\n x=mod(x*x,M)\n i=ishft(i,-1)\n end do\n end function powmod\nend program main", "language": "Fortran", "metadata": {"date": 1469760666, "filename_ext": "f", "original_language": "Fortran (gfortran v4.8.4)", "problem_description_relpath": "problem_descriptions/p04046.html", "problem_id": "p04046", "resource_group": "low_resource", "sample_input_relpath": "derived/input_output/data/p04046/input.txt", "sample_output_relpath": "derived/input_output/data/p04046/output.txt", "source_dataset": "Project CodeNet", "source_relpath": "data/p04046/Fortran/s308444173.f", "split_policy": "Global OOD problem IDs are disjoint from train, validation, and in-distribution test problem IDs.", "status": "Accepted", "submission_id": "s308444173", "user_id": "u017744950"}, "prompt_components": {"gold_output": "2\n", "input_to_evaluate": "program main\n implicit none\n integer(8),parameter::M=1000000007\n integer(8) h,w,a,b,i,asize\n integer(8),allocatable::fact(:),invf(:)\n integer(16)::i16=0\n\n read*,h,w,a,b\n asize=h+w\n allocate(fact(asize+1),invf(asize+1))\n\n fact(1:2)=1\n do i=1,asize\n fact(i+1)=mod(fact(i)*i,M)\n enddo\n invf(asize+1)=powmod(fact(asize+1))\n do i=asize,1,-1\n invf(i)=mod(invf(i+1)*i,M)\n enddo\n \n print*,mod(dot_product(&\n i16+mod(fact(h-a+b:h-a+w-1)*invf(b+1:w),M),mod(fact(w-b+a-1:a:-1)*invf(w-b:1:-1),M))*mod(invf(h-a)*invf(a),M),M)\n\n !end program main\ncontains\n function powmod(t) result(r)\n integer(8),intent(in)::t\n integer(8)x,i,r\n i=M-2\n x=t\n r=1\n do\n if ( i .eq. 0 ) exit\n if ( iand(i,1).eq.1 )then\n r=mod(r*x,M)\n endif\n x=mod(x*x,M)\n i=ishft(i,-1)\n end do\n end function powmod\nend program main", "problem_context": "Score : 400 points\n\nProblem Statement\n\nWe have a large square grid with H rows and W columns.\nIroha is now standing in the top-left cell.\nShe will repeat going right or down to the adjacent cell, until she reaches the bottom-right cell.\n\nHowever, she cannot enter the cells in the intersection of the bottom A rows and the leftmost B columns.
