Don't submit random answer. Computer science. How about we characterize a casualty substance: a casualty has a name (not really extraordinary) that comprises just of lowercase Latin letters and an integer doubt esteem. Toward the beginning of the program the client enters a rundown of n casualty names into an information base, every doubt esteem is set to 0. Then, at that point, the client makes questions of two sorts: 1 I x — set the doubt worth of the I-th casualty to x; 2 q — given a string q observe the most extreme doubt worth of a casualty whose name is a coterminous substring of q. Just to remind you, this program doesn't eliminate individuals, it just assists with looking for the names to record in a genuine scratch pad. Consequently, the rundown of the casualties in the data set doesn't change all through the questions. What are you sitting tight for? Compose that program now!
