Problem Statement The problem “Bubble sort using two Stacks” states that you are given an array a[ ] of size n. Create a function to sort the given array a[ ] using a bubble sort paradigm with two stack data structures. Example a[ ] = {15, 12, 44, 2, 5, …
Problem Statement You are given two arrays of integers arr1[] and arr2[]. The problem “Sort an array according to the order defined by another array” asks to sort the first array according to the second array so that the numbers in first array will be relatively sorted off all the …
Problem Statement Suppose you have an integer array. This array should be treated as a circular array. The last value of an array will be connected to the first array, an ⇒ a1. The problem “Maximize sum of consecutive differences in a circular array” asks to find out the maximum …
Problem Statement The problem “Find the largest multiple of 3” states that you are given an array of positive integers(0 to 9). Find the maximum multiple of 3 that can be formed by rearranging the elements of the array. Examples arr[] = {5, 2, 1, 0, 9, 3} 9 5 …
Problem Statement The problem “Check if a queue can be sorted into another queue using a stack” states that you are given a queue containing n elements, the elements in the queue are a permutation of numbers 1 to n. Check if this queue can be arranged in increasing order …
Problem Statement Suppose you have an integer array. The problem “Segregate even and odd numbers” asks to rearrange the array so that the odd and even numbers can be separated in two segments of the array. The even numbers be shifted into the left side of the array and odd …
Problem Statement Suppose you have an integer array. The problem “Rearrange an array in order – smallest, largest, 2nd smallest, 2nd largest, ..” asks to rearrange the array in such a way that the smallest number comes first and then the largest number, then second smallest and then the second …
Problem Statement Suppose you have an integer array. The problem “Rearrange array such that even positioned are greater than odd” asks to rearrange the array such the elements at even position in an array should be greater than the element just before it. Arr[i-1] < = Arr[i], if position ‘i’ …
