Editor to share with you what the basic algorithms of shell script programming are, I believe most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

Question 1: recursion and non-recursion of Fibonacci sequence

Non-recursive:

Recursion:

Note that the range of return under shell is 0-255. you cannot use return1 here.

Question 2: string interception cut

Question 3: finding the sum of 100 numbers

The first is non-recursive:

The second kind of recursion

The third tool

Question 4: find the maximum, minimum and average of the three numbers

These are all the contents of the article "what are the basic algorithmic programming of shell scripts?" Thank you for reading!
