Problem cb scholarship 2

#1

import java.util.;
public class Main {
public static void main(String args[]) {
Scanner cin = new Scanner(System.in);
int n = cin.nextInt(), m = cin.nextInt(), x = cin.nextInt(), y = cin.nextInt();
int low = 1, high = n,ans = 0;
while(low<=high){
int mid = (low+high)/2;
int req = midx, avail = m + (n-mid)*y;
if(avail>req){
low = mid +1;
ans = mid;
}else if(avail<req){
high = mid -1;
}else if(avail == req){
ans = mid;
low = mid + 1 ;
}
}
System.out.print(ans);
}
}====== still not getting all test cases right

@AbhishekAhlawat1102
take values in long because the product of integer can go out of range
