String Concatenation with Truncation

Background

Congcong is currently learning about string operations. He encountered an interesting problem that requires concatenating two strings with some special rules.

Problem Description

Given two strings, concatenate them and return the result. However, if the strings have different lengths, omit characters from the beginning of the longer string so it becomes the same length as the shorter string. For example, "Hello" and "Hi" yield "loHi". The strings may be of any length.

Input Format

Input is given from standard input in the following format.

Two strings $S_1$ and $S_2$, separated by a space.

Output Format

Output is printed to standard output in the following format.

The resulting concatenated string.

Sample

Hello Hi

loHi

Hello java

ellojava

java Hello

javaello

Sample Explanation
