arr have wrong type. Try to write "int **arr = (int *)malloc(sizeof(int)8);"

You should return a two dimentional array. (int **)

Hi. Fixed. Message did not display correctly. The size of array must be 8.

The last random test is the similar as the previous 100. Check your solution please.

Well, memory leaks is my headache! You shouldn't have to worry about it. Your job is to give me solution =)

Adorably!

This is strange, because there are 232 different solutions in Go. Please check your solution again.

Hi, thank you for your attention.
Fixed.

Well, it took 3 days, but that was awesome =)

Hi! In some cases my SortArray function really didn't work...Sorry about that. I just have fixed it =)

Thanks ;)

I thought this was clear from the description.
But I'm still corrected the example test cases for you =)

You can round up the distance to 10 decimal places. I corrected the description about that.
