Can you solve this real interview question? Number of Subarrays With GCD Equal to K - Given an integer array nums and an integer k, return the number of subarrays of nums where the greatest common divisor of the subarray's elements is k. A subarray is a
Can you solve this real interview question? GCD Sort of an Array - You are given an integer array nums, and you can perform the following operation any number of times on nums: * Swap the positions of two elements nums[i] and nums[j] if gcd(nums[i], nu
Goldbach’s cardinality (GC) of an even number means the number of ways the even number can be expressed as summation of 2 different primes. For example 30 = 7 + 23 = 11 + 19 = 13 + 17. So Goldba...UVA10738 Riemann vs Mertens【欧拉筛法】 One of the biggest, most mathematicians...
