Hacker Rank problem “Chocolate Feast”

I have uploaded a problem and solution that involves counting chocolates as you eat them, the tricky part is that as you eat a chocolate you get more. The general goal is to count the overall chocolates that you consume. I liked solving this problem because it has some small tricky points in the logic but the answer isn’t very lengthy. Watch the video to see a more in depth explanation of the problem and a way to come to a solution.

import java.util.Scanner;

public class Solution {

public static void main(String[] args) {
Scanner in = new Scanner(System.in);

int T = in.nextInt();

if (1 > T || T > 1000) {

for (int i = 0; i < T; i++) {
// money given
int N = in.nextInt();

// price of a chocolate
int C = in.nextInt();

// wrappers needed for a free chocolate
int M = in.nextInt();

int chocolates = N / C;

int wrappers = chocolates;

while (wrappers >= M) {
int newChocoloate = wrappers/M;
chocolates += newChocoloate;
wrappers = wrappers % M;
wrappers += newChocoloate;

System.out.println("" + chocolates);
