Assignment75

A Meera array is defined to be an array such that for all values n in the array, the value 2 * n is not in the array.

Examples

• {3, 5, ­2} is a Meera array because 3 * 2, 5 * 2 and ­2 * 2 are not in the array
• {8, 3, 4} is not a Meera array because for n = 4, 2 * n = 8 is in the array.

Write a function named isMeera that:

• returns 1 if its array argument is a Meera array
• otherwise it returns 0

The function signature is int isMeera(int[] a)

Solution

public class Assignment75 {
  public static void main(String[] args) {
    int result = isMeera(new int[]{3, 5, -2});
    System.out.println(result);

    result = isMeera(new int[]{8, 3, 4});
    System.out.println(result);
  }

  static int isMeera(int[] a) {
    for (int i = 0; i < a.length; i++) {
      for (int j = 0; j < a.length; j++) {
        if ((a[i] * 2) == a[j]) {
          return 0;
        }
      }
    }

    return 1;
  }
}
