Problem

You are given 3 numbers �,�, and �.

Determine whether the average of � and � is strictly greater than � or not?

NOTE: Average of � and � is defined as (�+�)2. For example, average of 5 and 9 is 7, average of 5 and 8 is 6.5.

Input Format

  • The first line of input will contain a single integer �, denoting the number of test cases.
  • Each test case consists of 3 integers �,�, and �.

Output Format

For each test case, output YES if average of � and � is strictly greater than �, NO otherwise.

You may print each character of the string in uppercase or lowercase (for example, the strings YeS, yEs, yes and YES will all be treated as identical).

Constraints

  • 1≤�≤1000
  • 1≤�,�,�≤10

3 7 2

YES
YES
NO
NO
YES

Explanation:

Test case 1: The average value of 5 and 9 is 7 which is strictly greater than 6.

Test case 2: The average value of 5 and 8 is 6.5 which is strictly greater than 6.

Test case 3: The average value of 5 and 7 is 6 which is not strictly greater than 6.

Test case 4: The average value of 4 and 9 is 6.5 which is not strictly greater than 8.

Test case 5: The average value of 3 and 7 is 5 which is strictly greater than 2.
