III-2 (CLRS 34.1-5) Show that if an algorithm makes at most a constant number of calls to polynomial-time subroutines and performs an additional amount of work that also takes polynomial time, then it runs in polynomial time.
WebSOLUTION. Suppose x and y are n bits long. Then all the intermediate numbers generated, up to the final answer xy, are O (n) bits long. Each iteration of the loop involves addition and subtraction of O (n)-bit numbers, and therefore takes O (n) time. The loop iterates y = O ( 2 n) times. Therefore the overall running time is O ( n 2 n ... WebNov 1, 2013 · Polynomial vs. Exponential Running Time Polynomial Running Time.
