Given three colors, such as R, G, and B, convert these RGB color to a hex color code. If the conversion is not possible, print -1....

Given an octal number as input, we need to write a program to convert the given octal number into equivalent decimal number....

Given string str of length N, the task is to check if the given string contains only special characters or not. If the string contains only special characters, then print “Yes”. Otherwise, print “No”....

Given a string s, find the length of the longest prefix, which is also a suffix. The prefix and suffix should not overlap....

Given a sorted array in which all elements appear twice (one after one) and one element appears only once. Find that element in O(log n) complexity....

Given an n x n matrix, where every row and column is sorted in non-decreasing order. Find the kth smallest element in the given 2D array....

Given an integer array of N elements. You need to find the maximum sum of two elements such that sum is closest to zero....

Given a sorted array of n distinct integers where each integer is in the range from 0 to m-1 and m > n. Find the smallest number that is missing from the array....

Given an array A[] consisting of N integers, the task is to check if it is possible to reduce array of at least length 2 such that all the elements in the array are equal. In an operation, choose any index i, and replace A[i] and A[i+1] with their XOR value....

Binary search is a popular algorithm used to search for an element in a sorted list efficiently. In this article we can going to understand why binary search has a time complexity of O(log2 n)....

Given an array A[] of size n where there are only unique elements in the array. We have to find the minimum concatenation required for sequence A to get strictly Longest Increasing Subsequence. For array A[] we follow 1 based indexing....
