Codechef - Weight Balance

Problem

No play and eating all day make your belly fat. This happened to Chef during the lockdown. His weight before the lockdown was w1​ kg (measured on the most accurate hospital machine) and after M months of lockdown, when he measured his weight at home (on a regular scale, which can be inaccurate), he got the result that his weight was w2​ kg (2>w2​>w1).

Scientific research on all growing kids shows that their weights increase by a value between x1​ and x2​ kg (inclusive) per month, but not necessarily the same value each month. Chef assumes that he is a growing kid. Tell him whether his home scale could be giving the correct results

Scientific research on all growing kids shows that their weights increase by a value between x1 and x2​​ kg (inclusive) per month, but not necessarily the same value each month. Chef assumes that he is a growing kid. Tell him whether his home scale could be giving correct results.

Input

• The first line of the input contains a single integer T denoting the number of test cases. The description of T test cases follows.
• The first and only line of each test case contains five space-separated integers w1​, w2​, x1​, x2​ and M.

Output

For each test case, print a single line containing the integer 1 if the result shown by the scale can be correct or 0 if it cannot.

Constraints

• 1 <= T <= 10⁵
• 1 <= w₁ < w₂ <= 100
• 1 <= x₁ <= x₂ <= 10
• 1 <= M <= 10

Explanation:

Example case 1: Since the increase in Chef's weight is 2 - 1 = 1 kg and that is less than the minimum possible increase of 1.2 = 2 kg, the scale must be faulty.

Example case 2: Since the increase in Chef's weight is 4 - 2 = 2 kg, which is equal to the minimum possible increase of 1.2 = 2 kg, the scale is showing correct results.

Example case 3: Since the increase in Chef's weight is 8 - 4 = 4 kg, which is equal to the maximum possible increase of 2.2 = 4 kg, the scale is showing correct results.

Example case 4: Since the increase in Chef's weight is 8 - 5 = 3 kg, which lies in the interval [1.2, 2.2]kg, the scale is showing correct results.

Example case 5: Since the increase in Chef's weight is 100 - 1 = 99 kg and that is more than the maximum possible increase 2.2 = 4 kg, the weight balance must be faulty.

Solution :

import java.util.*;

class Main {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        
        int T = sc.nextInt();
        
        while(T-- > 0) {
            int w1 = sc.nextInt();
            int w2 = sc.nextInt();
            int x1 = sc.nextInt();
            int x2 = sc.nextInt();
            int m = sc.nextInt();
            
            int ans = (w2 - w1 >= x1 * m && w2 - w1 <= x2 * m ? 1 : 0); 
            System.out.println(ans);
        }
        sc.close();
    }
}
