Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. I want to append characters to a string, but want to make sure all the letters in the final list are unique.

Now of course I have two solutions in my mind. So whenever I encounter a letter it will set the index to True. Afterwards I will scan the list and append all the ones that were set. It will have a time complexity of O n. Another solution would be using a dict and following the same procedure.

After mapping every char, I will do the operation for each key in the dictionary. This will have a linear running time as well. Since I am a Python newbie, I was wondering which would be more space efficient. Which one could be implemented more efficiently? Note that this doesn't guarantee the order in which the letters appear in the output, even though the example might suggest otherwise.

You refer to the output as a "list". If a list is what you really want, replace ''. Use an OrderedDict.

For completeness sake, here's another recipe that sorts the letters as a byproduct of the way it works:. Learn more.Given a string, determine if the string has all unique characters. Examples :. Approach 1 — Brute Force technique : Run 2 loops with variable i and j.

Compare str[i] and str[j]. If they become equal at any point, return false. Time Complexity : O n 2. Note: Please note that the program is case-sensitive. The idea is to maintain a boolean array for the characters. The indices represent characters. All the array elements are initially set to false. As we iterate over the string, set true at the index equal to the int value of the character.

If at any time, we encounter that the array value is already true, it means the character with that int value is repeated. Time Complexity: O n.

This approach is little tricky. Instead of maintaining a boolean array, we maintain an integer value called checker 32 bits. Return false in this case. Exercise : Above program is case sensitive, you can try making same program which is case insensitive i. Using Java Stream :.

Any number you give will pull either too many or too few characters from the text. Again, any number you give will pull either too many or too few characters from the text. The reality is that you often will need to the find specific characters in order to get the appropriate starting position for extraction.

With the FIND function, you can get the position number of a particular character and use that character position in other operations. In the example shown, you use the FIND function in conjunction with the MID function to extract the middle numbers from a list of product codes.

As you can see from the formula, you find the position of the hyphen and use that position number to feed the MID function. The FIND function has two required arguments. The first argument is the text you want to find.

The second argument is the text you want to search. By default, the FIND function returns the position number of the character you are trying to find.

If the text you are searching contains more than one of your search characters, the FIND function returns the position number of the first encounter. The result will be a number 4, because the first hyphen it encounters is the fourth character in the text string. Entering this formula in a cell will give you the two numbers after the first hyphen found in the text.Given a string, find the all distinct or non-repeating characters in it.

Start traversing from left side. For every character, check if it repeats or not. When the count becomes 1, return each character. Below is the implementation of above idea. Method 3 O n and requires one traversal The idea is to use two auxiliary arrays of size Assuming that characters are stored using 8 bits.
