Topic 1159: Word substitution

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.

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

Sample input

I Love Tian Qin

I

You

Sample output

You love Tian Qin
