Click and drag the given steps to their corresponding step names to find 11 mod 645 using the given algorithm procedure modular exponentiation (b: integer, n (ak-1ak 2...a1ao)2, m: positive integers) power b mod m for i 0 to 1 if a 1 then x (xy power mod m power :J (power power) mod m returns x tx equals br mod m) Step 1 Therefore, 11644 mod 645 can be calculated by first calculating 402 51 mod 645 *507, and then 507 446 mod 645 *1. 11 mod 645 *114 mod 645 x 11128 mod 645 x 11 mod 645 reducing modulo 645 512 at each step Step 2 116 mod 645 -402, 11129 mod 645 51, 11 mod 645 446 Therefore, 11644 mod 645 can be calculated by first calculating 451.121 mod 645 391, and then 391 226 mod 645 *1.
