Generate a Number with B Repeated Digits A

Given two integesr A and B, where 1 ≤ A ≤ 9 and 1 ≤ B ≤ 10, construct a number consisting of the digit A repeated exactly B times.

Input format: Two integers A and B, separated by a comma (possibly with whitespace).

Output format: A single integer formed by repeating A, B times.

Example Input:
1, 5

Example Output:
11111

Example Input:
3 ,4

Example Output:
3333

line = input().strip()
a, b = line.split(',')
digit = a.strip()
count = int(b.strip())
result = digit * count
print(result)

Convert a Number from Any Base to Decimal

Given a number represented as a string and its base, convert it to its decimal (base-10) equivalent.

Input format: A string representing the number and its base, separated by a comma.

Output format: The decimal value of the input number.

Example Input:
45,8

Example Output:
37

input_line = input().strip()
num_str, base_str = input_line.split(',')
base = int(base_str)
decimal_value = int(num_str, base)
print(decimal_value)

Count Digits and Lowercase Letters in a String

Given a string, count how many characters are digits (0–9) and how many are lowercase letters (a–z).

Input format: One line of text.

Output format: 共有X个数字，Y个小写字符, where X and Y are the respective counts.

Example Input:
helo134ss12

Example Output:
共有5个数字，6个小写字符

text = input()
digit_count = 0
lowercase_count = 0

for char in text:
    if '0' <= char <= '9':
        digit_count += 1
    elif 'a' <= char <= 'z':
        lowercase_count += 1

print(f'共有{digit_count}个数字，{lowercase_count}个小写字符')
