1. Explain what a selection statement is in a sentence or two along with an example. 2. Explain what a loops are in a sentence or two along with an example. 3. Explain what arrays are in a sentence or two along with an example. 4. Give an example that uses selection statements, loops, and arrays together to accomplish an important task. 5. Is it possible to replace a selection statement with a loop? Is it possible to replace a loop with a selection statement? Clearly and concisely argue your position.    No hand written and fast answer with explanation

1. Number Sorter in Matlab  Requirements: ●      Must be a console program ●      Reads integers from standard input (i.e from the user via the keyboard) until a number less than or equal to zero is input. This indicates the end of input. ●      Once end of input is detected, the program sorts all of the numbers in ascending order and displays them ●      You can choose any sort algorithms. For instance: ○      choose a random input, n, not yet sorted in the list of input values ○      go through the list of input values and place all values less than n to the left of n and all other values to the right of n ○      Once this is done then n is sorted, so go back and repeat the first step ○      Once all values n are sorted the entire list is sorted ●      You are not allowed the built-in function sort in Matlab to solve this problem 2) In 200 explain how the program function.    Note : manually solve the vector using any algorithm but don't use the built-in function  "sort " in matlab…
