# Sum of Consecutive Odd Numbers III

Adapted by Neilor Tonin, URI Brazil

Timelimit: 1

Read an integer N that is the number of test cases that follows. Each test case contains two integers X and Y. Print one output line for each test case that is the sum of Y odd numbers from X including it if is the case. For example:
for the input 4 5, the output must be 45, that is: 5 + 7 + 9 + 11 + 13
for the input 7 4, the output must be 40, that is: 7 + 9 + 11 + 13

## Input

The first line of the input is an integer N that is the number of test cases that follow. Each test case is a line containing two integer X and Y.

## Output

Print the sum of all consecutive odd numbers from X.

 Input Sample Output Sample 2 4 3 11 2 21 24
