Use MARS software to develop a well$-$documented MIPS Assembly program that:

$1)$ defines in the data segment a static matrix named mymat consisting of $6$x$8$ elements and initializes them with any float values;

$2)$ prints the elements of array mymat $8$ values per line separated by double colons :: ;

$3)$ prompts the user to enter from the KBD $2$ integer numbers col$1$ and col$2$ in the range $0$ to $7$ representing column numbers in the matrix mymat, validates the entered values and if wrong values are entered prints a proper error message and prompts the user to enter again.

$4)$ swaps the elements of columns specified by the values of col$1$ and col$2.$

$5)$ prints the elements of array mymat $8$ values per line separated by double dollar signs $$ ;

$6)$ creates a dynamic array and fills it with elements from row #$3$ of mymat.

$7)$ at the beginning of a new line, prints all elements of the obtained dynamic array separated by one star $*.$
