yb) Could you please write the needed SML (Standard Meta Language) code of this question?

it is needed to use map function and modules in SML;

map function is a method like this in an example:

Modules in SML are like this in an example:

ralagiapn Styles In SML (STANDARD META LANGUAGE), a matrix can be stored as a list of int lists such as the one given below: 1 2 3 4 5 6 7 8 9 10 11 12 val matrix-[(,2,3,41,(5,6,7,8],[9,10,11,12]1; Write an SML (standard meta language) module with visible/invisible separation to delete all the elements at the boundary of a matrix which includes the following: o Set of invisible functions to delete the first and last element of a list. e.g - delFrstlst ([1,2,3,4]); val it = [2,3] : int list A visible function which deletes the elements at the boundary of a matrix using the map function. e.g 5 2 3 4 8 1 2 3 4 5 7 9 8 7 6 will become 2 3 4 9 8 7 Sample Run: - open A; - delutrx(IIs,2,3,4,81, [1,2,3,4,51. 17,9,8.7,61.[8,8,8,8,811) val it = [[2,3,4],[9,8,7]] : int list list Notes: To edit and execute your SML program, do the following: a Download the Newjersey Standard ML compiler from the following addresses: a Type your program in any word processing software (Notepad, wordPad, Word, etc.) and a Test your functions using the compiler, and correct any errors from the word processing www.smlnj org www.processlist.com/info/110-smlnj html save it as a text file. Copy the written functions, and paste it onto the ML compiler screen using the menu (Edit-Paste) which appears when you right click on top of the screen. program. You can exit with Ctrl/z
