Count Set bits in an array of integers

assume you have an array of 5 integers and you want to count the numbers of set bits in all array elements , write a function to do that

Solution

Circular Bit Shift

Write two functions RL(data,n) which performs circular left shift on variable data by n bits , RR(data,n) which performs circular right shift on variable data by n bits
note: data is 1 byte variable
