Tricky sums indeed! (Posted on 2019-10-10) Difficulty: 3 of 5
Let the function O(n) denote the sum of natural numbers, i, less than or equal to n. However, this function has one trick - if the number to be added, i, is a power of 2, then instead of adding we subtract the number.

Find O(4)+O(5)+O(6)+...+O(10000)
