Suppose we have a number n. We perform any one of these operations arbitrary number of times −Replace n with n/2 when n is divisible by 2Replace n with 2n/3 when n is divisible by 3Replace n with 4n/5 when n is divisible by 5We have to count minimum number of moves needed to make number 1. If not possible, return -1.So, if the input is like n = 10, then the output will be 4, because use n/2 to get 5, then 4n/5 to get 4, then n/2 again to get 2 and n/2 again to get 1.StepsTo solve ...

John Lintner was a professor at the Harvard Business School who had researched on the factors that guide a company's dividend payout policy. Lintner came up with a formula for determining an optimal corporate dividend policy. His dividend policy model is founded on the principle that all companies tend to grow the dividend payouts to a target level and this process starts slowly in the beginning but takes a certain speed with passing time. This speed is known as the speed of adjustment.However, it has also been observed that there is a danger in increasing the speed of adjustment abruptly. ... Read More

Suppose we have an array A with n elements. Consider there is a password with n positive integers. We apply the following operations on the array. The operations is to remove two adjacent elements that are not same as each other, then put their sum at that location. So this operation will reduce the size of array by 1. We have to find the shortest possible length of the array after performing these operations.So, if the input is like A = [2, 1, 3, 1], then the output will be 1, because if we select (1, 3), the array will ...
