1111. Application of Word substitution strtok function

Title Description:

Enter a string to end with a carriage return (string length <=100). The string consists of several words, separated by a space, and all the words are case-sensitive. Now you need to replace one of these words with another word and output the replaced string.

Input:

Multiple sets of data. Each set of data input consists of 3 rows, the 1th line is a string with multiple words, the 2nd line is the word a to be replaced, and (length <=100) line 3rd is the word b that will be replaced. (length <=100) s, a, b the front and the back have no spaces.

Output:

Each test data output has only 1 rows, replacing all word a in s with the string after B.

Sample input:

Want someone to help Youyoui

Sample output:

I want someone to help you
