Sliding Window

# Statement

Given a string, `input_str`, return the length of the longest substring without repeating characters.

**Constraints:**

* $1$ $\leq$ `input_str.length` $\leq 10^5$
* `input_str` consists of English letters, digits, symbols, and spaces.

Let's solve the Longest Substring without Repeating Characters problem using the Sliding Window pattern.
