Given a range [a, b],
you are to find the summation of all the odd integers in this range. For
example, the summation of all the odd integers in the range [3, 9] is
3 + 5 + 7 + 9 = 24.
There can be at multiple test cases. The first line of input
gives you the number of test cases, T (
1T100).
Then T test cases follow. Each test case consists of 2 integers a and b (
0ab100)
in two separate lines.
For each test case you are to print one line of output - the
serial number of the test case followed by the summation of the odd integers in
the range [a, b].
