    Here is my one line Python solution!

    def saveThePrisoner(n, m, s):
    return (m + s - 1) % n if (m + s - 1) % n != 0 else n

    My TypeScript solution:

    function saveThePrisoner(n: number, m: number, s: number): number {
    const lastPrisioner: number = (s - 1 + m) % n;
    
    return lastPrisioner == 0 ? n : lastPrisioner;
}

    Here solution in c++, you can watch the explanation here : https://youtu.be/xoV2P0Pv9Fg

    Solution 1 : 

    int saveThePrisoner(int n, int m, int s) {
    int c = (m % n) + s - 1 ;
    if ( c > n) c -= n;
    if ( c == 0) return n;
    return c;
}

    Solution 2 : 

    int saveThePrisoner(int n, int m, int s) {
    return (m - 1  + s - 1 ) % n + 1;
}

    java 8 but there is error time error

    public static int saveThePrisoner(int n, int m, int s) {

    // Write your code here

    int i = 0;
    while (s < n) {
        i++;
        if (i == m) {
            return s;
        }
        s = (s + 1) % n;

    }
    return s;

}

    C# return (m+s-1) > n ?(((m+s-1)%n) == 0 ? n:(m+s-1)%n ):(m+s-1);
