Challenge 2: Fibonacci Sequence
Explore how to compute the first n Fibonacci numbers using Perl loops. Understand appending numbers to a string with spaces to produce correctly formatted output. This exercise strengthens loop handling and string manipulation skills in Perl.
We'll cover the following...
Problem statement
In this exercise, you have to compute the first n numbers of fibonacci sequence of a given $range.
There is a string variable $ans given in which you have to append all the computed Fibonacci numbers one by one.
Here’s a link showing how you can add values to a string.
Input
An integer.
Output
A string.
Sample input
$range = 6
Sample output
Then $ans should have the following stored in it for the sample input given:
Note Just like it is shown in the picture above, the values in the string should have spaces in between them. You can add a space by simply adding quotation marks with space in between them to your string, like this: " ".
Coding challenge
Write your code below. It is recommended that you try solving the exercise yourself before viewing the solution.
Good Luck!
