Suppose that a character string is represented by a list of single characters. Write a set of routines to manipulate such list as follows (in the following l1 , l2 and list are pointers to a header node of list representing a character string, str is an array of characters,, and i1 and i2 are integers): (c) strpsl( l1,,l2 ) to perform the str pos function of section 1.2 on two character strings represented by lists. This function returns an integers. (d) strvrfyl ( l1 , l2 ) to determine the 1st position of the string represented by l1 that is not contained in the string represented by l2 . this function return an integer. plzzz solve this and mail the simple solution text file on nainawan1@yahoo.com thanx
