Suppose we have two numbers A and B, we have to find the minimum positive number M so that M is divisible by A and the sum of the digits of M is same as B. So, if there is no such result, then return -1.So, if the input is ... Read More

Suppose we have an array A of numbers, in A the i-th number is the position where an island is present, and another integer k is given (1 ≤ k < N). Now, a person is standing on the 0-th island and has to reach the last island, by jumping ... Read More

Suppose we have width and height of N different rectangles; we have to find the minimum number of rectangles left after inserting one into another. So, if W1 and W2 be the width of rectangles R1 and R2 respectively. And H1 and H2 be the height of R1 and R2 ... Read More

Suppose we have one N X N matrix M, and this is filled with 1, 0, 2, 3, We have to find the minimum numbers of moves required to move from source cell to destination cell. While visiting through blank cells only, we can visit up, down, right and left.Cell ... Read More

Suppose we have two strings P and Q of same lengths with only lower case letters, we have to count the minimum number of pre-processing moves on string P are needed to make it equal to string Q after applying below operations −Select any index i and swap characters pi ... Read More

Suppose we have a given unsorted array A[0..n-1] of size n, we have to find the minimum length subarray A[s..e] so that by sorting this subarray the whole array will be sorted. So, if the array is like [2, 6, 4, 8, 10, 9, 15], then the output will be ... Read More

Suppose we have two numbers p and q, we have to find the minimum difference between any terms in the shifted infinite tables of p and q, these shifts are r and s, where r, s >= 0.So, if the input is like p = 7 and q = 17, ... Read More

Suppose there is a candy store where N different types of candies are available and the prices of all N different types of candies are given. The store also provides an attractive offer. According to this offer, we can buy a single candy from the store and get maximum of ... Read More

Suppose we have an array of size n, if the elements in the array, are in range from 0 to k-1. Where k is denoted as a positive integer and k max_val, thenmax_val := A[i]result := ireturn resultExample Let us see the following implementation to get better understanding − Live Demodef ... Read More
