It is guaranteed that for the given n the answer will not exceed 1018. Input WebMar 16, 2024 · If you divide natural numbers x by y i.e x/y, the remainder is always smaller than y. '%' in C++ gives the 'remainder' of such a division. So the line a [i] % j == j basically checks if some number divided by j gives the remainder j, which is not possible. I believe what you really want to check is if a [i] is a complete square of j.

WebMar 15, 2024 · In this problem, we are given an array divisors[] consisting of N integers which are the divisors of a number Num. Our task is to find the number from its divisors. The divisor array does not include 1 and the number. Let’s take an example to understand the problem, Input divisors[] = {3, 25, 5, 15} Output 75 Explanation WebTo make more divisors, we could multiply by 2,3, or 5. This will take us to 24, with 8 divisors, 36 with 9, or 60 with 12. So the increase in 3 2 .41. For going to 36 it is 3 2 3 .369 So we get a better return by going to 24. But for going to 5 it is 2 − 1 = .43, even better.
