| 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 ≤T ≤100). Then T test cases follow. Each test case consists of 2 integers a and b (0 ≤a ≤b ≤100) | |
| 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]. | |
