Question 3: Symbol Table and Hashed String (30\%) You are given the list of key:value pairs, and a hashed string. Recover the hashed string to its original text. Your program should read the input from the file, and output the answer to another file. The first argument is the input file name, while the second argument is the output file name. Name your program as "lab4-q3.c". Input file: A positive integer n(n50), indicating the number of key:value pairs in the symbol table. Following n lines, the key and value pairs are separated by a colon. Then, one more line for the hashed string. You can assume that the colon does not appear in the keys and the values. Each line has at most 100 characters. However, keys and values may contain spaces. Output file: Output the original texts. You can assume that the hashed string can be uniquely decoded. Sample Input: 4 1:I 01: Love 001:Data 000 : Structures 101001000 Sample Output: ILoveDataStructures
