The area of the rectangle is calculated as a product of its sides. All rectangles have four sides such that opposite sides are equal. For calculating the area we require length and breadth as two sides. So that we can get desired result −Area rectangle = length X breadthWe are ... Read More

A linked list is a linear data structure in which elements are linked via pointers. Each element or node of a linked list has a data part and link, or we can say pointer to the next element in sequence. The elements can take noncontiguous locations in memory.We are given ... Read More

We are given with an array. The array need not be sorted. The task is to find the maximum difference between adjacent elements of that array in its sorted form. So the first thing is to sort the array in increasing or decreasing order. Then we will iterate the array ... Read More

Probability Pi= (No. of Favourable Outcomes) / (Total no. of Outcomes).Given is a number N which is the number of containers present. And we have N copies of two numbers X and Y. The task is to divide copies of one number X into N containers such that the probability ... Read More

We are given with a sum of sides of a cuboid. A cuboid has three sides length, breadth and height. The volume of cuboid is calculated as a product of all three sides.Volume of Cuboid = Length X Breadth X HeightThe maximum volume can be achieved if all three sides ... Read More

The task is to maximize the value of number A by replacing some of its digits with digits present in another number B. No digits will be replaced if A’s value cannot be maximized.Note − a digit from B can be used only once.Let’s now understand what we have to ... Read More

For the given two arrays each of size N, the task is to find the maximum sum by choosing X elements from array 1 and Y elements from array 2.Let’s now understand what we have to do using an example −Input arr1 = {1, 2, 3, 4, 5} ; X=2 arr2 ... Read More

We are given with a matrix of size n x n and a condition that a[i][j] = 0 and the task is to calculate the maximum difference of indices having a[i][j] = 0. So, we can clearly state that there must be at least one zero in a matrix.Input int matrix[][] ... Read More

Given the task is to divide an array arr[] into K consecutive sub-arrays and find the maximum possible value of maximum among the minimum of the K consecutive sub-srrays.Input arr[]={2, 8, 4, 3, 9, 1, 5}, K=3Output 9Explanation − The 3 consecutive sub arrays that can made are: {2, 8, 4, 3}, ...
