+Task 2: Format Phone Number
+
+Submitted by: [45]Mohammad Sajid Anwar
+     __________________________________________________________________
+
+   You are given a phone number as a string containing digits, space and
+   dash only.
+
+   Write a script to format the given phone number using the below rules:
+1. Removing all spaces and dashes
+2. Grouping digits into blocks of length 3 from left to right
+3. Handling the final digits (4 or fewer) specially:
+   - 2 digits: one block of length 2
+   - 3 digits: one block of length 3
+   - 4 digits: two blocks of length 2
+4. Joining all blocks with dashes
+
+Example 1
+
+Input: $phone = "1-23-45-6"
+Output: "123-456"
+
+Example 2
+
+Input: $phone = "1234"
+Output: "12-34"
+
+Example 3
+
+Input: $phone = "12 345-6789"
+Output: "123-456-789"
+
+Example 4
+
+Input: $phone = "123 4567"
+Output: "123-45-67"
+
+Example 5
+
+Input: $phone = "123 456-78"
+Output: "123-456-78"
