Given an array nums of a positive integer and a sum s, find the minimum size of a contiguous subarray of nums such that whose sum equals to or greater than s(given value). Example Input: nums[] = {2, 3, 1, 2, 4, 3} s = 7 Output: 2 {Subarray [4, …
In intersection of two arrays problem, we have given two arrays, we need to print their intersection(common elements). Example Input arr1[] = {1, 2, 2, 1} arr2[] = {2, 2} Output {2, 2} Input arr1 = {4, 9, 5} arr2 = {9, 4, 9, 8, 4} Output {4, 9} Algorithm …
In search in sorted rotated array problem we have given a sorted and rotated array and an element, check if the given element is present in the array or not. Examples Input nums[] = {2, 5, 6, 0, 0, 1, 2} target = 0 Output true Input nums[] = {2, …
Given an array nums containing (n + 1) elements and every element is between 1 to n. If there is only one duplicate element, find the duplicate number. Examples Input: nums = {1, 3, 4, 2, 2} Output: 2 Input: nums = {3, 1, 3, 4, 2} Output: 3 Naive …
Given an array of integers of size n+1 where each element of the array is between 1 and n (inclusive), there is one duplicate element in the array, find the duplicate element. Brute force method – Approach 1 for Find the Duplicate Element For every ith element run a loop …
An element search in sorted rotated array can be found using binary search in O(logn) time. The objective of this post is to find a given element in a sorted rotated array in O(logn) time. Some example of a sorted rotated array is given. Example Input : arr[] = {7,8,9,10,1,2,3,5,6}; …
We all have heard the saying “Bad Apple Ruins The Bunch”.First Bad Version is a problem that beautifully illustrates the same. Today we have a problem which is First Bad Version. One of the interns has made an nth bad commit due to which commits from n+1 have all been …
What is Peak Index in a Mountain Array Problem? An array can be said as a Mountain Array if it shows the following properties: The length of the given array is should be greater than or equal to 3 LENGTH >=3. There can be only one peak or largest element …
Problem Statement In the Degree of an array problem we have given a non-empty array of non-negative integers nums, the degree of this array is defined as the maximum frequency of any one of its elements. Your task is to find the smallest possible length of a (contiguous) subarray of nums, …
In the Search Insert Position problem, we have given an integer x and a sorted array a[ ] of size n. Find the appropriate index or position at which the given integer must be inserted if given integer, not in the array. If given integer present in the input array …
