i need the unimplemented parts please $!$

write a MIPS program that simulates the output shown below. The program contains some of required subroutines which perform specific tasks based on the following requirements: $$ A subroutine called displayMenu$()$ that displays the menu shown in the sample output. $$ A subroutine called computeSeries$()$ that computes the series based on the end of series value entered by the user. The subroutine should deal with the numbers as double or float numbers. $($See Sample output$)$ s $=1+1+1+1$ A subroutine called display$()$ that prints array elements. If the array is empty, the message "Array is empty" should be displayed $($See Sample output$).$ The main program will do the following: a$.$ Display a menu to allow the user to choose any option and perform the corresponding actions. See sample output. b$.$ If the user chooses option $1,$ the user will be prompted to enter the end of series and will call the subroutine computeSeries$()$ to compute the series. See sample output c$.$ If the user chooses option $2,$ another menu will be displayed which contains the following choices: $($See sample output$).$ If the user enters $1,$ the program will ask the user to enter a number and store it in the array. $($See sample output$)$ If the user enters $2,$ the program will call the subroutine display$().($See sample output$)$ If the user chooses option $3,$ the program will return to the main menu. d$.$ If the user chooses option $0$ from main menu, the program will print a final message and will exit. e$.$ The program should repeat until the user chooses option $0.$
