Population Count Description: The population count is the number of 1s (ones) in the binary representation of a non-negative integer. Population count is also known as pop count, popcount, sideways sum, and Hamming weight. Take the number from the user and display its Population Count. For example: Input 5 65 ->Output Explanation In Java <=> 2 ⇒2 (binary of 5 is 101, and it has total 2 ones in it) (binary of 5 is 1000001, and it has total 2 ones in it)

Passing Array as Argument

An array is a data structure that holds only fixed-size data and its contents are arranged in contiguous memory slots. The primary purpose of using an array is to store data items of the identical type together. An array can stockpile any one of the following types of data: int, float, char and so forth. The elements are stored from index 0, and the difference between the two indexes of the array is termed as an offset. The array has a fixed size. Once the size is defined during array declaration, it cannot be changed later.

The interest paid on a savings account is compounded daily. This means that if you start with startbal dollars in the bank, at the end of the first day you’ll have a balance ofstartbal * (1 + rate/365)dollars, where rate is the annual interest rate (0.10 if the annual rate is 10 percent). At the end of the second day, you’ll havestartbal * (1 + rate/365) * (1 + rate/365)dollars, and at the end of n days you’ll havestartbal * (1 + rate/365)ndollars. Write a program that processes a set of data records, each of which contains values for rate, startbal, and n and computes the final account balance.
