The Fibonacci Sequence problem is one of the logic-based programming problems that are fun to solve and also asked in technical interviews. We think it’s an excellent project to hone your arithmetic skills in any language of your choosing.
Sounds good? Let’s get started. In this article, you’ll learn how to print a Fibonacci sequence up to n terms and n value.
What Is a Fibonacci Sequence?
A Fibonacci sequence is a series of numbers where each number is the sum of the two preceding ones, starting from 0 and 1. In Mathematics, this sequence is denoted by Fn.
Fibonacci Sequence:
Printing the First n Fibonacci Numbers
Problem Statement
You’re given a number n. You need to print the Fibonacci sequence up to the first n terms.
Example 1: Let n = 5.
First 5 Fibonacci Numbers: 0 1 1 2 3
Thus, the output is 0 1 1 2 3.
Example 2: Let n = 7.
First 7 Fibonacci Numbers: 0 1 1 2 3 5 8
Thus, the output is 0 1 1 2 3 5 8.

Printing the Fibonacci Sequence Up to n Value
Problem Statement
You’re given a number n. You need to print the Fibonacci sequence to the closest value less than or equal to n.
Example 1: Let n = 38.
Fibonacci Sequence up to 38: 0 1 1 2 3 5 8 13 21 34
Thus, the output is 0 1 1 2 3 5 8 13 21 34.
Example 2: Let n = 91.
Fibonacci Sequence up to 91: 0 1 1 2 3 5 8 13 21 34 55 89
Thus, the output is 0 1 1 2 3 5 8 13 21 34 55 89.

Rectify Your Programming Mistakes
Everyone makes mistakes while programming. But these mistakes can lead to so many problems. It’s very important to write clean and efficient code while programming. How do you go about that?
You must avoid common programming mistakes like repetitive code, bad variable names, not using comments, language overload, not backing up code, writing complicated code, not planning in advance, not asking questions, etc. Rectifying these mistakes can help you to become a better programmer.
