Problem

Earth is under attack. You have to send the Earth Defense Force (EDF) messages that make the situation clear. The EDF's strongest forces are mechs, huge bipedal robots piloted by Japanese teenagers. For a message to read as urgent, it has to appear on the pilots' monitors in uppercase letters. The tachyon communication system the EDF uses can only send strings of lowercase alphabetic characters.

The lowercase alphabetic characters are the 26 letters a, b, c, d, e, f, g, h, i, j, k, l, m, n, o, p, q, r, s, t, u, v, w, x, y, z.

Write a program that converts the given message to uppercase.

Input

The first line contains a string of length $n$ made up of lowercase alphabetic characters. ( $1 \le n \le 10^6$ )

Output

Print the input string on one line with every letter converted to an uppercase letter.
