Question 4

Suppose you have an input character stream (StreamReader) and you have a list of pattens like ABCAS, ASGKT. KHTSD etc. You need to read the stream one by one character and you need to keep count on number of each pattern found so far and when EOF occures just print all the patterns along with count.

Example:

Input String: 011100010

Pattern 1: 011

Pattern 2: 010

Output:

011 => 1

010 => 1
