+/**
+ ### Problem Statement:
+ Write a function that takes two rectangles as inputs and determines if they overlap. Each rectangle is represented by its bottom-left corner (x1, y1) and top-right corner (x2, y2). The function should return `true` if the rectangles overlap and `false` otherwise.
+
+ ### Input:
+ - Each rectangle is represented by a tuple of four integers: `(x1, y1, x2, y2)`, where:
+   - `(x1, y1)` represents the coordinates of the bottom-left corner.
+   - `(x2, y2)` represents the coordinates of the top-right corner.
+
+ ### Output:
+ - Return `true` if the two rectangles overlap, `false` otherwise.
+
+ ### Constraints:
+ - You may assume that the edges of the rectangles are aligned with the X and Y axes (i.e., they are not rotated).
+ - Rectangles that share an edge or a corner are **not** considered to be overlapping.
+
+ ### Test Cases:
+
+ 1. **Test Case 1: Partially Overlapping**
+    ```swift
+    Input: rect1 = (0, 0, 4, 4), rect2 = (2, 2, 6, 6)
+    Output: true
+    ```
+
+ 2. **Test Case 2: Non-Overlapping**
+    ```swift
+    Input: rect1 = (0, 0, 2, 2), rect2 = (3, 3, 5, 5)
+    Output: false
+    ```
+
+ 3. **Test Case 3: One Rectangle Inside Another**
+    ```swift
+    Input: rect1 = (0, 0, 6, 6), rect2 = (2, 2, 4, 4)
+    Output: true
+    ```
+
+ 4. **Test Case 4: Touching at Edge (Non-Overlapping)**
+    ```swift
+    Input: rect1 = (0, 0, 4, 4), rect2 = (4, 0, 6, 3)
+    Output: true
+    ```
+
+ 5. **Test Case 5: Touching at Corner (Non-Overlapping)**
+    ```swift
+    Input: rect1 = (0, 0, 3, 3), rect2 = (3, 3, 6, 6)
+    Output: true
+    ```
