WebApr 11, 2024 · Your long int is likely a signed 32-bit integer type, which means the largest positive integer it can store is 2,147,483,647, but your sum adds up to 5,000,000,015. Because this is larger, integer overflow has occurred. Replace the long int type with long long int.Or to make the sizes of the types more explicit, include and use int64_t.
