Go language provides inbuilt support for bits to implement bit counting and manipulation functions for the predeclared unsigned integer types with the help of bits package. This package provides the OnesCount8() function which is used to find the number of one bits in a. To access the OnesCount8() function you need to add a math/bits package in your program with the help of the import keyword.
func OnesCount8(a uint8) int
Parameters: This function takes one parameter of uint8 type, i.e., a.
Return Value: This function returns the total number of one bits that are used to represent a.
Total number of one bits that are used to represent 5: 2
OnesCount8(00000100) = 1 OnesCount8(00001101) = 3
