JavaScript - Number of 0 bits in a binary representation
JavaScript Bit Manipulation: Exercise-3 with Solution
Write a JavaScript program to count 0 bits in the binary representation of a given integer.
Test Data:
(45) -> 2
(17) -> 3
(15) -> "Parameter value is not an Integer!"
Sample Solution:
JavaScript Code:
function Binary_Count_SetBits(a)
{
// check whether input is an integer
if (!Number.isInteger(a))
{
return('Parameter value is not an Integer!')
}
return a.toString(2).split('0').length - 1
}
console.log(Binary_Count_SetBits(45))
console.log(Binary_Count_SetBits(17))
console.log(Binary_Count_SetBits("15"))
Sample Output:
2 3 Parameter value is not an Integer!
