What does the following Python function do?
I% is the mod operator. // is integer division, i.e. division, followed by floor. For example, 7% 3 evaluates to 1, 7 // 3 evaluates to 2. Put differently, both functions execute the division algorithm; // finds the quotient, % the remainder. def function(b,n,d) defines a function with inputs bin and d.]
def funation (b,n, d) :
result - 1
while n > 0:
15n8 2 = 1:
result - result*b& d
n=n- 1
n = n 112
return result
It returns b' mod d using fast modular exponentiation
It returns the lowest common prime factor of b, n and d.
It executes the division algorithm n=bd+r and returns the value of r ("result")
It executes the division algorithm d-b+r and returns the value r (result
It return Ic(b, n, d)
