Given an array of integers nums sorted in non-decreasing order, find the starting and ending position of a given target value. If target is not found in the array, print. You must write an algorithm with O(log n) runtime complexity. Input F ...
Given two arrays A and B of equal size n, the task is to find if given arrays are equal or not. Two arrays are said to be equal if both of them contain same set of elements, arrangements (or permutation) of elements may be different though. Note ...
Given a matrix of size N x N. Print the elements of the matrix in the snake like pattern depicted below. Your task is to complete the function printSnakePattern which receives the input matrix and N as its p ...
John Watson knows of an operation called a right circular rotation on an array of integers. One rotation operation moves the last array element to the first position and shifts all remaining elements right one. To test the abilities of Sherlock , Wa ...
