Question

Use Algorithm 5 to find 32003 mod 99.

ALGORITHM 5 Fast Modular Exponentiation.
procedure modular exponentiation(b: integer, n = (ak-1ak-2... a₁ ao)2, m: positive integers)
x :=1
power := b mod m
for i:= 0 tok - 1
if a₁ = 1 then x := (x power) mod m
(power power) mod m
power
return x {x equals b" mod m}
