You have two strings A = A_1 A_2 ... A_n and B = B_1 B_2 ... B_n of the same length consisting of 0 and 1. The number of 1's in A and B is equal.
You've decided to transform A using the following algorithm:
* Let a_1, a_2, ..., a_k be the indices of 1's in A.
* Let b_1, b_2, ..., b_k be the indices of 1's in B.
* Replace a and b with their random permutations, chosen independently and uniformly.
* For each i from 1 to k, in order, swap A_{a_i} and A_{b_i}.
Let P be the probability that strings A and B become equal after the procedure above.
Let Z = P \times (k!)^2. Clearly, Z is an integer.
Find Z modulo 998244353.
Constraints
* 1 \leq |A| = |B| \leq 10,000
* A and B consist of 0 and 1.
* A and B contain the same number of 1's.
* A and B contain at least one 1.

Your task is to implement a double linked list.
Write a program which performs the following operations:
* insert x: insert an element with key x into the front of the list.
* delete x: delete the first element which has the key of x from the list. If there is not such element, you need not do anything.
* deleteFirst: delete the first element from the list.
* deleteLast: delete the last element from the list.
Notes
Template in C -->
Constraints
* The number of operations ≤ 2,000,000
* The number of delete operations ≤ 20
* 0 ≤ value of a key ≤ 109
* The number of elements in the list does not exceed 106
* For a delete, deleteFirst or deleteLast operation, there is at least one element in the list.
Input
The input is given in the following format:
n

Your task is to implement a double linked list.
Write a program which performs the following operations:
* insert x: insert an element with key x into the front of the list.
* delete x: delete the first element which has the key of x from the list. If there is not such element, you need not do anything.
* deleteFirst: delete the first element from the list.
* deleteLast: delete the last element from the list.
Notes

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
Your task is to implement a double linked list.
Write a program which performs the following operations:
* insert x: insert an element with key x into the front of the list.
* delete x: delete the first element which has the key of x from the list. If there is not such element, you need not do anything.
* deleteFirst: delete the first element from the list.
* deleteLast: delete the last element from the list.
Notes
Template in C -->
Constraints
* The number of operations ≤ 2,000,000
* The number of delete operations ≤ 20
* 0 ≤ value of a key ≤ 109
* The number of elements in the list does not exceed 106
* For a delete, deleteFirst or deleteLast operation, there is at least one element in the list.
Input
The input is given in the following format:
n
command1
command2
...
commandn
In the first line, the number of operations n is given. In the following n lines, the above mentioned operations are given in the following format:
* insert x
* delete x
* deleteFirst
* deleteLast
Output
Print all the element (key) in the list after the given operations. Two consequtive keys should be separated by a single space.
Examples
Input
7
insert 5
insert 2
insert 3
insert 1
delete 3
insert 6
delete 5
Output
6 1 2
Input
9
insert 5
insert 2
insert 3
insert 1
delete 3
insert 6
delete 5
deleteFirst
deleteLast
Output
1

Provide a correct Python 3 solution for this coding contest problem.
Your task is to perform a simple table calculation.
Write a program which reads the number of rows r, columns c and a table of r × c elements, and prints a new table, which includes the total sum for each row and column.
Constraints
* 1 ≤ r, c ≤ 100
* 0 ≤ an element of the table ≤ 100
Input
In the first line, two integers r and c are given. Next, the table is given by r lines, each of which consists of c integers separated by space characters.
Output
Print the new table of (r+1) × (c+1) elements. Put a single space character between adjacent elements. For each row, print the sum of it's elements in the last column. For each column, print the sum of it's elements in the last row. Print the total sum of the elements at the bottom right corner of the table.
Example
Input
4 5
1 1 3 4 5
2 2 2 4 5
3 3 0 1 1
2 3 4 4 6
Output
1 1 3 4 5 14
2 2 2 4 5 15
3 3 0 1 1 8
2 3 4 4 6 19
8 9 9 13 17 56 | instruction | 0 | 74,951 | 5 | 149,902 |
"Correct Solution:
```
r, c = map(int, input().split())
matrix = [list(map(int, input().split())) for _ in range(r)]
for i in range(r):
matrix[i].append(sum(matrix[i]))
matrix.append(list(map(sum, zip(*matrix))))
# matrix.append([sum(i) for i in zip(*matrix)])
for row in matrix:
print(' '.join(str(e) for e in row))
