Given a set of n distinct bolts and n corresponding nuts, (a one-to-one correspondence exists between bolts and nuts), we want to find the correspondence between them. We are not allowed to directly compare two bolts or two nuts, but we can compare a bolt with a nut to see which one is bigger. Design an algorithm to find the matching pairs of bolts and nuts in time O(n2) for the worst-case scenario. Your algorithm should have an expected running time of O(n log n).

Given a collection of n nuts, and a collection of n bolts, each arranged in an increasing order of size, give an O(n) time algorithm to check if there is a nut and a bolt that have the same size. You can assume that the sizes of the nuts and bolts are stored in the arraysNUTS[1..n] and BOLTS[1..n], respectively, where NUTS[1] < ··· < NUTS[n] and BOLTS[1] < ··· < BOLTS[n]. Note that you only need to report whether or...
