Answer 1

def countDigits(s) :
    size = len(s)
    
    if (size == 0) :
        print("String is empry", end ="")
        return
    
    digit_frequency = [0] * 10

    for i in range(size):
        if (s[i].isdigit()) :
            digit_frequency[ord(s[i]) - ord('0')] += 1 
    
    for i in range(10):
        print(i, ":", digit_frequency[i], "times")
    

s = "python23c++4523java23988rust82215"
