Task 2: Multiply by Two
Submitted by: [46]Mohammad Sajid Anwar
__________________________________________________________________
You are given an array of integers, @ints and an integer $start..
Write a script to do the followings:
a) Look for $start in the array @ints, if found multiply the number by 2
b) If not found stop the process otherwise repeat
In the end return the final value.
Example 1
Input: @ints = (5,3,6,1,12) and $start = 3
Output: 24
Step 1: 3 is in the array so 3 x 2 = 6
Step 2: 6 is in the array so 6 x 2 = 12
Step 3: 12 is in the array so 12 x 2 = 24
24 is not found in the array so return 24.
Example 2
Input: @ints = (1,2,4,3) and $start = 1
Output: 8
Step 1: 1 is in the array so 1 x 2 = 2
Step 2: 2 is in the array so 2 x 2 = 4
Step 3: 4 is in the array so 4 x 2 = 8
8 is not found in the array so return 8.
Example 3
Input: @ints = (5,6,7) and $start = 2
Output: 2
2 is not found in the array so return 2.
