WebMar 13, 2024 · Approach: If X is a multiple of all the elements of the first array then X must be a multiple of the LCM of all the elements of the first array. Similarly, If X is a factor of all the elements of the second array then it must be a factor of the GCD of all the elements of the second array and such X will exist only if GCD of the second array is divisible by the … WebJun 20, 2015 · I had faced a interview question to find the gdc (greatest common divisor) for an integer array of element in optimised way : Sample case : a [] = { 10,20,19,15,13} Result = 1 sample case : a []= {9,21,12,15,27} Result : 3. I have submitted following result during the interview. But he asked to optimise the same. Solution which I proposesd:

WebFeb 23, 2024 · Now he is being asked to split the array such that in all the subarrays the GCD of the starting and the ending element is greater than 1. As this procedure is expensive so Ninja needs to create the minimum number of subarrays that satisfy the above property. If it is not possible to create such subarrays then return -1. WebNov 19, 2016 · One way to do this can be: Let us find all the factors except 1, of all the numbers, in 1 iteration of the array.
