this is the link to my code
You are initializing char array ‘str’ of size 10 and taking input of length more than than. Thatswhy you are getting the error.
Initialize ‘str’ of size 10^6. As mentioned in problem constraints.
Btw your solution is not efficient.
It is a simple observation, for a string with length more than 10, the answer will be zero bcz there are only 10 distinct digits(0,1,2,3,4, . . . ,8,9). So string with length more than 10 will contain repeated digits. And absolute difference between them will be 0 that will make your answer 0. 
So, you have to calculate only for (length <=10).
