How do you print duplicate characters from a string?

Question

Can anyone tell me please how can we find duplicate characters from a string in Python, C, C#, Kotlin etc...

Answer 1

We don't give ready made codes here.. You have to attach your own attempt for further help..

But,

One of the way would be to take the characters in a map and keep track of the count of each characters.

Then, if the character count is greater than 1 then that means you found duplicate characters.

This is not exactly the code you want but hope this will give you some inspiration..
