Move all negative elements to one side of array – Suppose you have an array of integers. It consists of both negative and positive numbers and the problem statement asks to shift/move all the negative and positive elements to the left of the array and to the right of the …
Suppose, we have given two integers array of same size n. Both of the arrays contain positive numbers. The problem statement asks to maximize the first array by using the second array element keeping the second array as a priority (elements of the second array should appear first in output). …
The problem “Find whether an array is subset of another array” states that you are given two arrays arra1[] and array2[]. The arrays given are in an unsorted manner. Your task is to find whether the array2[] is a subset of array1[]. Example arr1= [1,4,5,7,8,2] arr2= [1,7,2,4] arr2 [] is …
The problem “Sorting using trivial hash function” states that you are given an integer array. An array can be containing both negative and positive numbers. The problem statement asks to sort the array using Trivial Hash Function. Example arr[] = {5,2,1,3,6} {1, 2, 3, 5, 6} arr[] = {-3, -1, …
Problem statement In the problem ” Largest Perimeter Triangle” we are given an array with n values. All the values are positive integers. Question ask to find the maximum perimeter of the triangle that we can construct from these values. In case it is not possible to construct the triangle …
Problem statement In the problem ” Can Make Arithmetic Progression From Sequence” we are given an array, now we need to answer if it is possible to generate an Arithmetic Progression by rearranging the sequence. Example arr = [3,1,5] true Explanation: We can rearrange the array as{1,3,5} which forms an …
Problem statement In the problem ” Shuffle String” we are given a String and an array. The array contains the new indices of the character of the string. So array[i] represents a new position of character at ith position of the string. In “Shuffle String” we need to shuffle the …
Suppose, we have given an integer array. The problem “Count of index pairs with equal elements in an array” asks to find out the no of pair of indices (i,j) in such a way that arr[i]=arr[j] and i is not equal to j. Example arr[] = {2,3,1,2,3,1,4} 3 Explanation Pairs …
Suppose you have an array of integers. The problem “Find Sum of all unique sub-array sum for a given array” asks to find out the sum of all unique sub-arrays (Sub-array sum is the sum of each sub-array’s elements). By unique sub-array sum, we meant to say that no sub-array …
The problem “Find number of pairs in an array such that their XOR is 0” state that supposes, we have given an array of integers. The problem statement asks to find out the number of pairs present in an array, which has the pair Ai XOR Aj = 0. Note: …
