Write a pseudocode description of the printLCS ) algorithm, which prints the longest common subsequence of two strings x and y. Your algorithm should take as input the completed 11cs [] [] integer array of longest common subsequence lengths, and the two strings x and y. (So, you do not have the path[] [ array - see Lecture 19, slides 100 and 101.) Your algorithm must return the specific string corresponding the length found in cs [n] [m] and it should run in O(n + m) time, where n is the length of x and m is the length of y
