Hi I Am TKD ,I am an explorer and researcher ,Today I will speak How To Implement an algorithm To Determine If A string has all unique characters without additional data structures?

i am going to show how to find if a string has all unqiue characters just by using Boolean arrays and with out any additional data structures

First let me write the code in front of you

Now I will debug the code
Create a new boolean array of 256 characters to account for basic ascii and extended ascii characters
Iterate through the string we are testing
Get the numerical (ascii) value of the character in the `str` at position `i`.
If char_set[val] has been set, that means that this character was already present in the string. (so in string 'hello' this would be true for the second 'l')
If the character hasn't been encountered yet (otherwise we would have returned false above), then mark this particular character as present in the string
If the function hasn't returned false after going through the entire string that means that each character is unique - thus returning true
