So I've just been reading that the proof that sum of all natural numbers 1 + 2 + 3 + 4... = -1/12 the mathematical proof is sound but it causes some problems like: how come the sum of 2 natural numbers is a fraction??? my answer is because we aren't dealing with a natural...
The problem goes like this: It's a game between two players, there are two piles of coins with different coin values. (piles may be empty) In one turn a player can take a single top-most coin from any of the two piles.The game ends when there are not coins in both piles. I've...

Your task is to calculate the sum of values over all possiblegood paths. Since this number can be very large, output it modulo109+710^9 + 7109+7. Twogood pathsare considered different if the starting cell differs or there exists an integeri∈[1,k]i \in [1, k]i∈[1,k]such that...
Codeforces--598A--Tricky Sum(数学) Description In this problem you are to calculate the sum of all integers from1ton, but you should take all powers of two with minus in the sum. For example, forn = 4the sum is equal to - 1 - 2 + 3 - 4 = -...
