MADODDSUM - Easy Odd Sum |
Hablu likes odd numbers a lot. So he wants the sum of all odd numbers in range [a, b]. That is, find the sum of all odd numbers i such that (a ≤ i ≤ b). Seems easy right? Because it is.
Input
The first and only line will contain 2 integers a, b where (0 ≤ a ≤ 108) and (0 ≤ b ≤ 108).
Output
In one line, output the value of the sum
Example
Input: 0 9 Output: 25

I'm curious how the heck I'm getting a "wrong" answer on this, would be nice to see feedback on a case that is wrong! :( ... even using unsigned long for the sum preventing overflow :( ... This should be so simple :( |
