1823. Find the Winner of the Circular Game
Problem Explanation
Explanation:
To solve this problem efficiently, we can simulate the game using a circular linked list approach. We can create a circular linked list of size n and then iterate through the list while removing elements until only one element (the winner) remains. We can achieve this without actually creating the linked list by using a formula that calculates the position of the winner directly.
The formula to find the winner is:
Solution Code
class Solution {
public int findTheWinner(int n, int k) {
int winner = 0;
for (int i = 2; i <= n; i++) {
winner = (winner + k) % i;
}
return winner + 1;
}
