Given an array of unique integers, print the array in such a way that the first element is first maximum and second element is first minimum and so on. We have to Rearrange an array in maximum minimum form using Two Pointer Technique. Examples: Input : arr[] = {7, 1, 2, 3, 4, 5, 6} Output : 7… Read More »
Given a list of n integers and consider another list which has n-1 “<” or “>” operators. Your task is to form a valid sequence by rearranging the initial list such that it follows the operator’s sequence in the final list. “vector” is a list containing integers “operators” is a list containing operators constraints: 2<=n<=1000. Examples: Input :… Read More »
Given an array of size N. The task is to find the maximum and the minimum element of the array using the minimum number of comparisons. Examples: Input : A[]={4,2,-1,5,0,-5,7,3,6} Output : Min Element -5 Max Element 7 Input : A[]={3,8,4,2,6,9} Output : Min Element 2 Max Element 9 Approach: The idea is to use the Two Pointer… Read More »
Given an array in increasing order and a target, return indices of two numbers such that they add up to the target. You have to return an array of indices where the zeroeth index value is less than first index value. Note: Your returned answers (both index1 and index2) are not zero-based. You may assume that each input… Read More »
Given a sorted array arr, remove the duplicates in the array itself such that duplicates appear at most twice in the given array arr and print the new length and modified array arr. Examples: Input: arr[] = {0, 0, 7, 7, 7, 7, 8, 9, 9} Output: 7 arr[] ={0, 0, 7, 7, 8, 9, 9} Explanation: The… Read More »
