In this problem, we are given an array arr[] consisting of n integer values. Our task is to create a program to find the equilibrium index of an array.Equilibrium Index is the index at which the sum of all elements before the index is the same as the sum of all ... Read More

Equidigital numbers are mathematically special numbers in which the number of digits in the number is equal to the number in its prime factorization.In this problem, we are given an integer value n. Our task is to create a program to all equidigital numbers up to n.Let’s take an example ... Read More

In this problem, we are given an integer n. Our task is to create a program to find the count of integers from i = 0 to n, where sum is equal to XOR i.e. (n+i) = (n^i).Let’s take an example to understand the problem, Input:  n = 4Output: 4Explanation: Considering all ... Read More

In this problem, we are given an array of n elements. Our task is to create a program to count the number of operations to equalize an array using elements only.We need to count the number of adding or subtraction operations that will be performed to make all the elements ... Read More

In this problem, we are given the coordinates of a polygon. Our task is to create a program to check whether the given polygon is equable or not.Equable Shape is the shape whose perimeter is equal to the area of the shape.Let’s take an example to understand the problem, Input: polygon[][] = ...

In the binary file and data management, endianness is the sequence of bytes of a digital data inside the computer memory.In computer memory there are two type of endian order, Big-endian system stores the most significant byte of the data.Small-endian systems store the least significant byte of the data.Read More

In this problem, we will understand the conversion of 2-D array to 1-D array. We will see how to store the elements of a 2-D array to a 1-D array.Here, the size of 1-D array is same as the total number of elements in 2-D array which is n*m.In programming ... Read More
