Unique Characters Checker

You are given a string s. Your task is to determine whether every character in the string is unique. In other words, check if no character appears more than once. If all characters are distinct, print True; otherwise, print False.

The problem can be mathematically expressed as: Determine if \[ |s| = |\{ s_i : 1 \leq i \leq n \}\| \] where s is the input string of length n and s_i represents its i-th character.
