Chocolate Feast

  • pankaj113 + 2 comments

    I tried again :-)

    import java.io.; import java.util.; import java.text.; import java.math.; import java.util.regex.*;

    public class Solution {

    public static void main(String[] args) {
    Scanner in = new Scanner(System.in);
    int t = in.nextInt();
    for(int a0 = 0; a0 < t; a0++){
        int n = in.nextInt();
        int c = in.nextInt();
        int m = in.nextInt();
        int chocs = n/c;  //chocolates bought with Money
        int wrapper = chocs; //wrappers from chocolate
        int ex_chocs = wrapper/m; //chocolates from wrappers
        while(wrapper>=m){
            ex_chocs = ex_chocs+(wrapper/m + wrapper%m)/m;
            wrapper = wrapper/m;
        }
        System.out.println(chocs+ex_chocs);

    }
}

    }

      @pankaj113, You can simplify/reduce your code by moving this line

      int ex_chocs = wrapper / m;

      inside while loop, like so:

      while(wrapper >= m) {
    int ex_chocs = wrapper / m;
    wrapper = ex_chocs + wrapper % m;
    chocs += ex_chocs;
}
System.out.println(chocs);

        @cesarjom Elegant and straight-forward. Thanks for sharing.

        can be further simplified

        while(w>=m){
    chocs+=w/m;
    w=w/m+(w%m);
}
