1) Program A and B are analyzed and found to have worst- case running times no greater than 150nlog2n and n2 respectively.Answer the folloWing questions if possible.. i) which program has the better guarantee on the running time,for larger values of n(n>10000) ? ii) which program has the better guarantee on the running time,for small values of n(n<100) ? iii) which program will run faster on average for n =1000 2) wRite a program to compute the number of collisions required in a long random sequence of insertions using linear probing ,quadratic probing and double hashing 3) what is the optimal way to compute A1 A2 A3 A4 A5 A6 where the dimensions of the matrices are A1:10*20 A2 : 20 * 1 A3 : 1 * 40 A4 : 40*5 A5 : 5 * 30 A6 : 30 X 15

I am given a sequential algorithm that does a routine search on an unordered list. N = 20. The probability that the value x does NOT appear in the list is exactly 60%, and the probability that x DOES appear is 40%. The 3 questions that I could not get were: A) What is the avg number of element comparisons performed when n = 20 and x does NOT appear in the List. (my answer was 20, is this correct?) B) What is the avg number of element comparisons peformed when n = 20 and x DOES appear in the list? C) What is the avg number of element comparisons performed when n = 20. This should be a single number answer they said.
