This problem asks us to find the first non-repeating character in a given string. For example, if the string is "GeeksforGeeks", then the first non-repe ating character is 'f'.

A.I. Evaluation of the Solution

The candidate's solution is correct and uses a dictionary to store the characters and their counts. The time complexity of this solution is O(n) because the dictionary is iterated through once. The space complexity of this solution is O(n) because the dictionary is the same size as the input string.
