Problem Statement In the “Check if all Rows of a Matrix are Circular Rotations of Each Other” problem we have given a char matrix, write a program to find whether all rows are circular rotations of each other or not. If all rows are circular rotations of each other print …
Problem Statement In the “Find the point where a monotonically increasing function becomes positive first time” we have given a function “int f(unsigned int x)” which takes a non-negative integer ‘x’ as input and returns an integer as output. The function is monotonically increasing with respect to the value of x, i.e., the …
Problem Statement In the “Find the Row with Maximum Number of 1’s” problem we have given a matrix(2D array) containing binary digits with each row sorted. Find the row which has the maximum number of 1’s. Input Format The first line containing two integers values n, m. Next, n lines …
Problem Statement In the “Find the Peak Element from an Array” problem we have given an input array of integers. Find a peak element. In an array, an element is a peak element, if the element is greater than both the neighbours. For corner elements, we can consider the only …
Problem Statement In the given unsorted array, find the pair of elements in the given array with given difference n. Example Input arr[] = {120, 30, 70, 20, 5, 6}, difference(n) = 40 Output [30, 70] Explanation Here the difference of 30 and 70 is equal to the value of …
Problem Statement We have given an array that contains n integers. We have to find the first repeating element in the given array. If there is no repeated element then print “No repeating integer found”. Note: Repeating elements are those elements that come more than once. (Array may contain duplicates) …
Problem Statement There can be multiple repeating numbers in an array but you have to find the first repeating number in a given array (occurring the second time). Example Input 12 5 4 2 8 9 7 12 5 6 12 4 7 Output 5 is the first repeating element …
Problem Statement In find the first and second smallest elements problem we have given an array of integers. Find the first and second smallest integers from an array or find two smallest numbers from an array. Example Input 7, 6, 8, 10, 11, 5, 13, 99 Output First Smallest is …
