Problem Statement In the “Maximum Sum of Non Consecutive Elements” given array, you need to find the maximum sum of non-consecutive elements. You can not add immediate neighbor numbers. For example [1,3,5,6,7,8,] here 1, 3 are adjacent so we can’t add them, and 6, 8 are not adjacent so we …
Problem Statement In the “Find Smallest Missing Number in a Sorted Array” problem we have given an integer array. Find the smallest missing number in N sized sorted array having unique elements in the range of 0 to M-1, where M>N. Example Input [0, 1, 2, 3, 4, 6, 7, …
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 Multiplication of Previous and Next: In the given array replace every element with the product of next and previous elements to it. And for the first element(a[0]) we need to replace it with the product of next and itself, for the last element(a[n-1]) we need to replace it …
Problem Statement In a product array puzzle problem we need to construct an array where the ith element will be the product of all the elements in the given array except element at the ith position. Example Input 5 10 3 5 6 2 Output 180 600 360 300 900 …
Problem Statement We have given an array of containing different elements or no repeated elements present in the array. Find all pairs with a given difference. If there is no any pair with given different then print “No pair with given different”. Example Input 10 20 90 70 20 80 …
Problem Statement In find all common elements in given three sorted arrays problem, we have given three sorted arrays and you have to find common numbers that is present in all three arrays. Example Input: ar1[] = {1, 5, 10, 20, 40, 80} ar2[] = {6, 7, 20, 80, 100} …
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 We have an array of containing N integers which may be positive or negative. We have to print all distinct elements of the array. In other words, we can say that if a number occurs more than one time then we print only that number once. Example Input …
Problem Statement We have given an array of n integers in which we have to find the maximum difference between two elements such as larger element comes after smaller. Example Input 4 7 2 18 3 6 8 11 21 Output 19 Approach 1 for Maximum difference between two elements …
