please solve this algithm Imagine an array with size $20$ and the worst$-$case scenarios of bubble sort $($array is sorted but

in descending order$)$ and selection sort $($array is already sorted$).$

a$.$ How much assignment operation do both algorithms do to sort the array?$(15$ pts$)$

b$.$ Assume each assignment operation takes $5ms.$ How long does it take to sort the

array with both algorithms? $(10$ pts$)$

Note: Neglect operations inside for loop and if statement.
