Problem: A and B play a game with a pile of stone. A starts the game and they alternate moves. In each move, a player has to remove at least one and no more than sqrt of number stones from the pile. So, for example if a pile contains 10 stones, then a player can take 1,2,3 stones from the pile. Both A and B play perfectly. The player who cannot make a valid move loses. Now you are given the.

You are playing the following Nim Game with your friend: There is a heap of stones on the table, each time one of you take turns to remove 1 to 3 stones. The one who removes the last stone will be the winner. You will take the first turn to remove the stones. Both of you are very clever and have optimal strategies for the game. Write a function to determine whether you can win the game given.

The one who removes the last stone will be the winner. You will take the first turn to remove the stones. Both of you are very clever and have optimal strategies for the game. Write a function to determine whether you can win the game given the number of stones in the heap. For example, if there are 4 stones in the heap, then you will never win the game: no matter 1, 2, or 3 stones you remove.

Game theory related problems in LeetCode. The problem is in the form of a game with multiple choices in one step. The game’s target is either 1. to win the other player or 2. reach a target with.

Both of you are very clever and have optimal strategies for the game. Write a function to determine whether you can win the game given the number of stones in the heap. For example, if there are 4 stones in the heap, then you will never win the game: no matter 1, 2, or 3 stones you remove, the last stone will always be removed by your friend.
