Odd Sum
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.

Input
There can be at multiple test cases. The first line of input gives you the number of test cases, T ( 1
T100).
Then T test cases follow. Each test case consists of 2 integers a and b (
0ab100)
in two separate lines.
Output
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].Sample Input
2 1 5 3 5
Sample Output
Case 1: 9 Case 2: 8
Cara untuk selesaikan problem ni hanya perlu tambah nilai ganjil.. Yang penting ianya inclusive.. Perlu tambah dari nilai dari integer pertama yang di input, sehinggalah sampai input integer yang kedua.
