They have an input which goes through a series of computations, and finally produces an output. One could even say a cooking recipe is an algorithm (indeed this analogy is sometimes mentioned to CS students to intoduce them to the topic).

The length can be any natural number (i.e., zero or any positive integer). A particularly useful string for some programming applications is the empty string, which is a string containing no characters and thus having a length of zero. A substring is any contiguous sequence of characters in a string.}]]> 2018-09-27 17:35:27 UTC https://padlet.com/juliawozniak273/bkonev9ov1ed/wish/286659376 juliawozniak273 https://padlet.com/juliawozniak273/bkonev9ov1ed/wish/286661026 2018-09-27 17:38:04 UTC https://padlet.com/juliawozniak273/bkonev9ov1ed/wish/286661026
