Write down a summation version of the run-time of each of the following algorithms and then figure out and prove the asymptotic complexity (0- set) of that run-time function. (a) FUNCTION W. (n = N) x i 0 1 WHILE i < n DO x++ i 5i RETURN (T) (b) FUNCTION W(n. N) 140 FOR 1 TO DO j+3 WHILE j < i DO RETURN (T) x++ j+2j
