Array − An array is a container of elements of the same data type, whose elements are 0 indexed.In this problem, we will use an array of integers. And check if all the elements are greater than the given number or not. Here we will check if all elements of ... Read More

An unsigned number represented as a stream of bits is written in binary form.The binary form of 54 is 110110.Adding two numbers using bits, we will add their binary form using the binary addition logic.Rules for bit addition is −0+0 = 01+0 = 10+1 = 11+1 = 0 with carry ... Read More

In programming, the ++ operator is the increment operator that increases the value of the operand by 1. We can add two numbers using this operator by adding 1 to the number a, b number of times.Example, Input: a = 31 , b = 4 Output: 35Explanation − adding 1 ... Read More

A number represented by the array is stored in such a form that each digit of the number is represented by an element of the array. For example, Number 234 in array is {2, 3, 4}.To add to such numbers we will first add number at the least significant digit ... Read More
