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
N = input()
D = {}
for ch in N:
if ch in D:
D[ch] += 1
else:
D[ch] = 1
cnt = 0
for ch in D:
if D[ch] > 1:
cnt += 1
print(cnt)
