A number is strictly a smaller element means the number should be less than by a minimum difference is 1 and similarly strictly greater element means the number should be greater than by a minimum of difference 1. Here we have given an array of integers of size n and ... Read More

We are given an integer B and A, and we have to convert the number K from 0 to exactly B by applying the given operations in the minimum steps. We can increase the current number K by 1 i.e. K = K + ... Read More

We are given an array it this problem and we have to remove all the elements of the array with the minimum cost required. We have to remove two elements at a time and add them to the total cost. Also, we can remove the third number without any cost ... Read More

We are given an array that contains the binary numbers that are '0', and '1' only. We have to make a one-bit set of the given array which was earlier not the set bit (there will be at least a bit present in the given array which will not be ... Read More

There are two players, X and Y, who are playing a game. X will start the first and can pick 1 stone from the set of an unlimited number of stones after that Y will start and can pick the 2 stones, then X will pick 3, and so on ... Read More

Peaks are defined as the point or index in the array where are both left and right sides values are smaller than the value of that index. And Troughs are defined as the point or index of the array where are both left and right sides values are greater than ... Read More

We are given two strings and we have to check if it is possible to convert the first string to another by performing any number of times a particular given task. The tasks that can be performed on the given first string only and the tasks are: ... Read More

We are given three strings of equal size equal to 2*N, where N is an integer. We have to create a string of the size 3*N and at least two strings from the given strings be the subsequence of it. Also, the given strings are binary strings which means they ... Read More

Set bits are the bits in the binary representation of the number which are '1'. The binary representation of the number contains only two digits '1' and '0', also it may be present in the form of a string. We are given a string, the binary representation of a given ... Read More

In a string, a subsequence is a string that can be formed by deleting some character from it which means it contains some character from the string may be all or none and all will be present in the same order of the string. Among two strings we have to ... Read More
