Question

Repeated Numbers

Eren wants to decode a number.After lots of trial and error, he finally figured out that the number is a count of repeated single-digit integers.

Write a program to help Eren print the decoded number given a string of integers N.

Input

The first line contains a string of integers N.

Output

The output contains a single integer representing count of repeated numbers in the input.

Explanation

For N = 212311 ,

1 and 2 are repeated.Therefore, the output is 2.

Sample Input1

212311

Sample Output1

2

Sample Input2

111

Sample Output2

1

Note: This site already given answer but it was not executin

answer:

N = input()

digits = [0]*10

for ch in N:

  d = int(ch)

  digits[d] += 1

cnt = 0

for d in digits:

  if d > 1:

    cnt += 1

print(cnt)

error:

Traceback (most recent call last):

 File "main.py", line 5, in <module>

  d = int(ch)

ValueError: invalid literal for int() with base 10: ' '

Answer 1

N = int(input())

digits = [0]*10

while N > 0:
    d = N%10
    N //= 10
    digits[d] += 1

cnt = 0
for d in digits:
  if d > 1:
    cnt += 1

print(cnt)
