You are given four integers a, b, c and d. Determine if there’s a rectangle such that the lengths of its sides are a, b, c and d (in any order).
- 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 four space-separated integers a, b, c and d.
For each test case, print a single line containing one string "YES" or "NO".
- 1 ≤ T ≤ 1,000
- 1 ≤ a, b, c, d ≤ 10,000

Looks very easy in first go. However there is a catch you need to see. Else gives WA in beginning.
