Suppose we have an array called houses and have another value k. Here houses[i] represents the location of the ith house along a street, we have to allocate k mailboxes in the street, and find the minimum total distance between each house and its nearest mailbox.So, if the input is ... Read More

Suppose there is an array of size m, represents m houses in a small city, each house must be painted with one of the n colors (the colors are labeled from 1 to n), And some houses are already painted, so no need to paint again. Those houses which are ... Read More

Suppose, we are given a m x n grid box, where each cell has a board that is positioned either from the top-right to bottom-left, or from the top-left to the bottom-right. Now from the top cells, a ball is put into the box and we have to check if ... Read More

Suppose we have two strings, s and t, we have to check whether s and t are close or not. We can say two strings are close if we can attain one from the other using the following operations −Exchange any two existing characters. (like abcde to aecdb)Change every occurrence ... Read More

Suppose, we are asked to implement a queue that can push and pop values at the front, middle, and back.We have to implement a pair of functions to push and pop for all three cases. We have to implement another function that shows the full queue at a given time.So, ... Read More

Suppose, we are given n number of points as (x, y). A vertical area is an area that is extended infinitely along the y-axis. We have to find out the vertical area between two points such that no other point is inside the area and is the widest.So, if the ... Read More

Suppose there is an array called forbidden, where forbidden[i] indicates that the bug cannot jump to the position forbidden[i], and we also have three values a, b, and x. A bug's home is at position x on the number line. It is at position 0 initially. it can jump by ... Read More

Suppose, there is a family that consists of members from different generations. Such as the family has a father, his children, and their grandmother. But births and deaths happen in each family.The eldest member of the family is considered the head. So, when the 'head' member dies, their direct successor ... Read More

Suppose there is a Ferris wheel with four cabins and each cabin can contain four passengers. The wheel rotates counter-clockwise, and for each rotation, it costs 'run' amount of money. We now have an array 'cust' that contains n items and each item i signifies the number of people waiting ... Read More

Suppose we have a string s with only two characters 's' and 't'. We can delete any number of characters of s to make the string balanced. We can say, s is balanced when there is no pair of indices (i, j) such that i < j and s[i] = ... Read More
