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>.
def capitalize_word(word):
    if len(word) < 1:
        return word  # Handle empty string or single-character strings
    
    first_letter = word[0].upper()
    rest_of_word = word[1:]
    
    return first_letter + rest_of_word

# Get user input
input_word = input("Enter a word: ")

# Capitalize the word
capitalized_word = capitalize_word(input_word)
print("Capitalized word:", capitalized_word)
