The bits.Sub() Function in Golang is used to find the difference of a, b and borrow, i.e. diff = a – b – borrow. Here the borrow must be 0 or 1; otherwise, the behavior is undefined. To access this function, one needs to imports the math/bits package in the program. The return value of the borrowOutput will be always 0 or 1 in any case.
func Sub(a, b, borrow uint) (diff, borrowOut uint)
Parameters: This function takes three parameters of uint type, i.e., a, b, and borrow. The value of borrow parameter is either 1 or 0
Return Value: This function return two values of uint type, i.e., diff and borrowOut. Here diff contains the result of a – b – borrow and borrowOut is either 1 or 0.
Diff: 1 BorrowOut : 0
Number 1: 10 Number 2: 5 Borrow : 1 Diff: 4 BorrowOut : 0
