Write Python code to solve the task. Ashishgup and FastestFinger play a game. They start with a number n and play in turns. In each turn, a player can make any one of the following moves: * Divide n by any of its odd divisors greater than 1. * Subtract 1 from n if n is greater than 1. Divisors of a number i...
Step 1: We need to determine the optimal moves for both players in order to decide the winner. Step 2: We can start by identifying the winning and losing states for each test case. Step 3: We should also consider the constraints on the input and how it affects our solution approach. Step 4: After identifying the ga...

Write Python code to solve the task. Everyone loves a freebie. Especially students. It is well-known that if in the night before exam a student opens window, opens the student's record-book and shouts loudly three times "Fly, freebie, fly!" β€” then flown freebie helps him to pass the upcoming exam. In the night before...
Step 1: We need to find the maximal number of students visited by the freebie based on the time interval during which the freebie was near the dormitory. Step 2: We can start by sorting the students' sacrament times in ascending order. Step 3: Then, we can iterate through the sorted times and count the number of stu...

Each operation is described with two integers l and r and a character c: Petya removes from the string all characters c on positions between l and r, inclusive. It's o...
Step 1: We need to keep track of the string and perform operations that remove characters from the string within a given range. Step 2: We can start by creating a function to remove characters from the string based on the given range and character. Step 3: Then we can iterate through the operations and update the st...

Write Python code to solve the task. Recently a dog was bought for Polycarp. The dog's name is Cormen. Now Polycarp has a lot of troubles. For example, Cormen likes going for a walk. Empirically Polycarp learned that the dog needs at least k walks for any two consecutive days in order to feel good. For example, if k ...
Step 1: We need to determine the minimum number of additional walks Polycarp should do and the appropriate schedule. Step 2: We can start by calculating the number of additional walks needed for the next n days so that Cormen will feel good every day. Step 3: Then we can develop a schedule that satisfies the conditi...

Write Python code to solve the task. Blackjack is a type of card game played in casinos, where the game is played using cards with numbers from 1 to 13. The score of each card is decided as follows. * 1 is 1 point or 11 points * From 2 to 9, the score is as written. * 10 points from 10 to 13 There are several parti...
Step 1: We need to calculate the score for each hand of cards based on the rules provided. Step 2: We can start by creating a function to calculate the score of a hand. Step 3: The score calculation should consider the special case of having aces (cards with value 1) and choose the maximum total score while not exce...

Write Python code to solve the task. You have a knapsack with the capacity of W. There are also n items, the i-th one has weight w_i. You want to put some of these items into the knapsack in such a way that their total weight C is at least half of its size, but (obviously) does not exceed it. Formally, C should satis...
Step 1: To solve this problem, we need to select appropriate items to put in the knapsack to satisfy the given conditions. Step 2: We can iterate through the list of weights and check if any single item meets the condition for filling the knapsack just right. Step 3: If not, we need to find a combination of items th...
