3. The Ownership System & Move Semantics

Overview: Each value has a single owner. Moving a value invalidates the previous owner.

Concept & Syntax Guide

Rust prevents double-free and use-after-free bugs at compile time. When a heap value is assigned to another variable, ownership moves, making the old variable inaccessible.

Hands-On Practice Exercise

Clone a Heap String to Prevent Move

Given `let s1 = String::from("FitPulse");`, use `.clone()` to copy it to `s2` so both can be printed.

Target Output: Templates: FitPulse, FitPulse

Hint: Check syntax carefully and make sure your code contains: Templates: FitPulse, FitPulse
