Here is the Python solution:

def change(st):
    answer_string = [
        '0','0','0','0','0','0','0','0','0','0','0','0','0',
        '0','0','0','0','0','0','0','0','0','0','0','0','0',
    ]

    upper_alphabets = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ'

    for char in st:
        upper_index = 0
        for upper_alphabet in upper_alphabets:
            if upper_alphabet == char or upper_alphabet.lower() == char:
                answer_string[upper_index] = '1'
            upper_index += 1

    return "".join(answer_string)
