Count set bits in a range in C++
We are given an integer number let’s say, num and the range with left and right values. The task is to firstly calculate the binary digit of a number and then set the loop from the left digit till the right digit and then in the given range calculate the set bits.Set bits in a binary number is represented by 1. Whenever we calculate the binary number of an integer value then it is formed as the combination of 0’s and 1’s. So, the digit 1 is known as set bit in the terms of the computer.Input − int number ...
Read MoreCount of parallelograms in a plane in C++
We are given a plane containing points forming the parallelogram and the task is to calculate the count of parallelograms that can be formed using the given points. In parallelograms opposite sides of a quadrilateral are parallel and therefore opposite angles are equal.Input −int a[] = {0, 2, 5, 5, 2, 5, 2, 5, 2} Int b[] = {0, 0, 1, 4, 3, 8, 7, 11, 10}Output − Count of parallelograms in a plane − 3Explanation − we are given with the (x, y) points and using these points we can form a count of 3 parallelograms as shown in ...
