You’re assuming that total strings generated will be around 100
But for string length 8 total possible permutations are 8! which is much higher than 100
Please fix this
If your doubt is resolved please close it.

One more error
You’re checking duplicates before inserting each time
Your complexity is N^2 where N is 8!
insert all elements in a set instead
