Given an array arr of integers, check if there exist two indices i and j such that :

+ + + +

 

+

Example 1:

+ +
Input: arr = [10,2,5,3]
+Output: true
+Explanation: For i = 0 and j = 2, arr[i] == 10 == 2 * 5 == 2 * arr[j]
+
+ +

Example 2:

+ +
Input: arr = [3,1,7,11]
+Output: false
+Explanation: There is no i and j that satisfy the conditions.
