Air traffic landing statistics is another interesting data. A dataset is available

(https://data.world/sanfrancisco/fpux-q53t). However, there might be other dataset as well. Your

goal is to find for more dataset and then identify task (that generates some meaningful insight)

and prepare that dataset accordingly.

Instructions regarding the Projects:

a. Data collection

b. Data Preprocessing and Cleaning

c. Data Visualization

d. Data Statistics(Summary of statistics)

e. Hypothesis Testing

f. Prediction Task(Using Machine Learning Model)

Any kind of interesting facts about data(e.g., kind of different studies which can be done

using the collected data), innovative ideas, and/or research ideas (Manipulation or

enhancements of existing techniques for better results) will also be considered during

evaluation and will be highly appreciated.

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)

reorder of string

eren wants to modify a string. the string can contain only positive integers. he wants to change the string in such a way thet the smaller numbers should appear before the bigger numbers.

given string write a program to help eren to modify the string.
