Capitalization is writing a word with its first letter as a capital letter. Your task is to capitalize the given word.

Note, that during capitalization all the letters except the first one remains unchanged.
A single line contains a non-empty word. This word consists of lowercase and uppercase English letters. The length of the word will not exceed 10<sup class="upper-index">3</sup>.
# import io, os, sys
# 
# def cap(s):
#     if ord(s[0]) >= 97 and ord(s[0]) <= 122:
#         return chr(ord(s[0])-32) + s[1:]
#     return s
# input = sys.stdin.readline
# s = input()
# sys.stdout.write(caps) + '\n')

s = input()
print(s.capitalize())
