You are given a string which contains some special characters. You also have set of special characters. You are given other string (call it as pattern string). Your job is to write a program to replace each special characters in given string by pattern string. You are not allowed to create new resulting string. You need to allocate some new memory to given existing string but constraint is you can only allocate memory one time. Allocate memory exactly what you need not more not less.
