- Write a function using scheme language, that takes in a list of values as input and returns true if list contains two equal values otherwise return false.For example: If the list (1 5 1 5) should print #t If the list (4 2 3 6) should print #f Note: You can not use any built-in function and use pure scheme language also use recursion to acheive this. The soultion should be runnable in Dr. Racket IDE. Please don't give solution in any other language it should be Scheme language only.Write a function using scheme language, that takes in a list of values as input and returns true if list contains two equal values otherwise return false.For example: If the list (1 5 1 5) should print #t If the list (4 2 3 6) should print #f Note: You can not use any built-in function and use pure scheme language also use recursion to acheive this.Write a Scheme function that computes the mean of a simple list of integers. For example, the function that takes (1 2 3 4) will return 2.5. (hint: you may use the built-in method (length lst) to get the list length)
- Write a function removeN which takes three arguments called N, E and L (where L is a list) and returns a list equal to L but with the first N occurrences of E in that list removed. Note: only first N occurrences of E must be removed, not all occurrences! If there are less than N occurrences of E in the list, then all occurrences of E should be removed. Using scheme language Test Result (removeN 2 'a '(a b a c a d a)) (b c a d a) (removeN 4 'a '(a b a c a d a)) (b c d)I need help writing an emacs/lisp function Write a function in Lisp that takes one parameter which we can assume to be a list. The function should print all the elements of the list using the function princ and a space between them. Use the function mapc for this purpose. Show a few examples of testing this function. Show one example using the function apply and one using the function funcall.Using the Scheme dialect of Lisp, write a single function that squares each item of a list, then sums all the items in the list, and then lastly, takes square root of the sun.
- Write a lisp function that prints out the calendar for the current month. This function should take 2 parameters: the day of the week that the month starts from as an index (0 for Sunday, etc.) and the number of days in the month. For example, if you call the function (calendar 2 30) Print the initial of each day on the first line using the list of days defined at the previous exercise, the capitalized symbol-name as before, and the function substring to extract the first letter of the string. For example, the call: (substring "Sunday" 0 1) returns the string "S".A. Write a Scheme function that returns the number of zeros in a given simple list of numbers.B. Write a Scheme function that returns the reverse of its simple list parameter.C. Write a Scheme predicate function that tests for the structural equality of two given lists. Two lists are structurally equal if they have the same list structure, although their atoms may be different.Write a working function in Lisp: a function that takes one parameter that you can assume to be a symbol named after a day of the week (no need to check it), such as 'monday, and returns the symbol for the next day. For example, (next-day 'tuesday) should return the symbol 'wednesday. Implement this function with a complex conditional.
- Suppose you have a list of key/value pairs (i.e., a nested list where each element of the list is a (key value)pair. For example, the list might look like this: '((France Paris) (France Nice) (Spain Madrid) (Poland Krakow) (Poland Warsaw)) (Notice that the keys need not be unique for this problem.) Write a function named first-occurrence in Scheme that takes a key and a list then returns the value of the first item on the list with a matching key. Return '() if none of items on the list has a matching key. You must use either fold or reduce to do the vast majority of the work. You may use the built-in foldmethod by adding the line (require 'list-lib), or you can use your own implementation. The built-in fold function has parameters in this order: action partial-result lst. You may assume that the list contains an element with the key to be updated. For example, (first-occurrence 'Germany '((France Paris) (Germany Bonn) (Germany Berlin))) should return 'Bonn (first-occurrence 'Poland…4-Write a Scheme procedure that takes a list and returns the sum of the odd- numbers that are less than 8 in the list. For example, (sumodd '(1 (2 () 6) 3 (5) 8)) returns 9. Then, Manually trace your procedure with the provided example. Please study provided examples foreign the lecture notes to learn how you should manually trace our procedure.Write a function using scheme language, that takes in a list of values as input and produces the same list as output but without duplicate values. So, the list (1 5 1 5) should become (1 5). using scheme language
