ORIGINAL Q: Instead of reading in an entire list N1,N2,⋯N1,N2,⋯ all at once, some algorithms (depending on the task to be done) can read in only one element at a time and process that single element completely before inputting the next one. This can be a useful technique when the list is very big (e.g., billions of elements) and there might not be enough memory in the computer to store it in its entirety. Write an algorithm that reads in a sequence of values v≥0, one at a time, and computes the average of all the numbers. You should stop the computation when you input a value of V = −1. Do not include this negative value in your computations; it is not a piece of data but only a marker to identify the end of the list.

write the pseudocode of the function SEARCH_MUSIC_GENRE (head, genre) that receives as input arguments the head of the list of playlists and the name of a music genre (e.g. Pop, Rock, Blues, etc). If a node with that music genre exists in the main list, the function SEARCH_MUSIC_GENRE (head, s) must return the memory address of the first element of the corresponding playlist. If a node with that music genre does not exist in the main list, the value NULL must be returned.
