1823. Find the Winner of the Circular Game

Leetcode Solutions

Recursion and Mathematical Approach

  1. Define a recursive function solve that takes n and k as arguments.
  2. If n is 1, return 0 as the base case.
  3. Otherwise, call solve(n-1, k) to get the winner's position in a circle with one less friend.
  4. Adjust the returned position by adding k and taking modulo n to get the correct position in the current circle.
  5. The findTheWinner function calls solve with n and k and adds 1 to the result to convert from 0-indexed to 1-indexed position.
