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.
