The content of the matrix Need is : a. Allocation – Available b. Max – Available c. Max – Allocation d. Allocation – Max

Solve first 3 functions please protoypes are in the header.

Task 7: Consider the following puzzle vector: Element 1 Element 2 Element 3 Element 4 2 1 3 2 1 2 3 2 Design and explain a concrete data structure that implements this puzzle vector. The data structure must only consist of elements that can store an integer or a pointer to another element or null - elements can be indexed if they are contiguous in memory as with an array. You can draw the data structure and explain how the allowed operations of vectors are implemented on this concrete data structure - additional pointers can be created to traverse lists. One approach could be to use arrays, or linked lists, or another approach completely.

Project 2 – Vaccine DistributionIntroductionThis project will require you to write a function that handles matrix data using loops and indexing. Do not any built-in functions, such as sort or find.You work for a government entity and have been tasked with processing information about vaccinesupply needs. Vaccines are being distributed to people in 5 phases, based on their age, pre-existingconditions, and jobs that place them at risk. Vaccines must be distributed in 2 doses. You haveinformation about the following:- Anonymous information from people in the vaccine site’s region:o The phase that they are eligible for.o Whether they have had 0, 1, or 2 doses of the vaccine.o How many days it has been since the last dose of the vaccine for an individual.- The number of vaccine doses that will be available each day.You have been tasked with determining a distribution plan for determining which individuals will get thevaccine on a given day.ProcedureWrite a function that takes 2 inputs:- A…
