Write a function named first_non_repeating_letter that takes a string input, and returns the first character that is not repeated anywhere in the string.For example, if given the input ‘stress’, the function should return ‘t’, since the letter t only occurs once in the string, and occurs first in the string.As an added challenge, upper- and lowercase letters are considered the same. Problem Statement: Given a string or stream of characters, find the first non-repeating character, which implies getting the first character that is not occurring more than once in the string.

Given an input stream of A of n characters consisting only of lower case alphabets. The task is to find the first non repeating character, each time a character is inserted to the stream. If there is no such character then append '#' to. In this section we are going to find the first unique or non-repeating character from a string or stream of characters. There are multiple ways to solve this problem. We will try to create two different program for the same stream of characters. Method 1: Using function. The algorithm itself is fairly straightforward. You could improve performance for large inputs where non-repeating characters occur relatively late by keeping a list of characters in order of their first occurrence. You then only need to iterate that list after building the character-counts dictionary, instead of iterating the full input again..

Extension: An extension to this problem can be to print all the repeating characters in the string. This is not as simple as the above problem.. Explanation: “a” – From the stream, the first character is a, So at this point, the first non-repeating character is ‘a’. “ab” – When b comes, Still the first non-repeating character is ‘a’. “aba” – This time the character is a. Character a is repeated twice so the first non repeating character is ‘b’. “abad.
