Convert while loop to recursive-CodePudding

I have the following code and I want to make the while loop recursive since I need a recursive function of the nth root of a number but I don't know how to do it

public static void main(String[] args) {
    float x = 0f;
    int n = 0;
    float result = 0f;
    float aux = 0.00001f;
    Scanner sc = new Scanner(System.in);

    x = sc.nextFloat();
    n = sc.nextInt();

    if (n == 0) {
        result = 1;
    } else {
        while (nthPower(result, n) < x) {
            result = result   aux;
        }
    }

    System.out.printf("%.4f\n", result);
}

public static float nthPower(float x, int n) {
    float tmp = 1;

    for (int i = 0; i < n; i  ) {
        tmp = tmp * x;
    }

    return tmp;
}

CodePudding user response：

Actually, you should break the function down first:

A loop has a few parts:

the header, and processing before the loop. May declare some new variables
the condition, when to stop the loop.
the actual loop body. It changes some of the header's variables and/or the parameters passed in.
the tail; what happens after the loop and return result.

foo_recursive(params){
    header
    return foo_recursion(params, header_vars)
}

foo_recursion(params, header_vars){
    if(!condition){
        return tail
    }

    loop_body
    return foo_recursion(params, modified_header_vars)
}
