Concatenate Two Strings

Given two strings provided on separate lines, your task is to concatenate them and output the result. This problem is a fundamental exercise in string manipulation and basic I/O handling. You may encounter strings that include letters, numbers, spaces, or even special characters.

The solution should be able to handle empty strings as valid input. Use the LaTeX format for any formulas if needed, though this problem doesn't require much math.

inputFormat

The input consists of two lines read from standard input (stdin). The first line contains the first string and the second line contains the second string. Note that either or both strings can be empty.

outputFormat

Output a single line to standard output (stdout) containing the concatenation of the two input strings without any additional spaces or characters.
