Write a function equal that returns whether two sets are equal.

equal :: Set -> Set -> Bool

Solutions

Expert Solution

import Data.List

equal :: (Eq set) => [set] -> [set] -> Bool ---function declaration

equal a b = null (a \\ b) && null (a \\ b) -------function definition

main = do ------main function

putStrLn "check the given sets are equal or not:"

print("[1,2,3,4] and [1,2,3,4] are equal or not ")

print(equal [1,2,3,4] [1,2,3,4]) --- function calling

print("[2,3,4] and [1,2,3,4] are equal or not ")

print(equal [2,3,4] [1,2,3,4]) -----functioncalling

program and sample output

1. Write a Racket function (set-equal? L1 L2) that tests whether L1 and L2 are equal. Two sets are equal if they contain exactly the same members, ignoring ordering (or in other words, two sets are equal if they are a subset of each other). For example (set-equal? '(1 (2 3)) '((3 2) 1)) ---> #t (set-equal? '(1 2 3) '((3 2)1)) ---> #f (set-equal? '(1 2 3) '((1 2 3))) ---> #f 2. Two common operations on sets are...

Write a Haskell function combine :: Int -> Int -> Int -> Int with the following behavior: • When x, y, and z all correspond to digit values (i.e., integers between 0 and 9, inclusive), combine x y z returns the integer given by the sequence of digits x y z. (That is, x is treated as the digit in the hundreds place, y is treated as the digit in the tens place, and z is treated as the digit...

Can someone show me how to write a Haskell function using snd on a list of tuples to create a new list of just the second element in each tuple? Ex. [(‘m’, False), (‘w’, False), (‘n’, True)] would evaluate to [False, False, True].

In Python: Write a function called sum_odd that takes two parameters, then calculates and returns the sum of the odd numbers between the two given integers. The sum should include the two given integers if they are odd. You can assume the arguments will always be positive integers, and the first smaller than or equal to the second. To get full credit on this problem, you must define at least 1 function, use at least 1 loop, and use at...

Write a program in java to determine whether a given function F from the set {0,1,2,3,...,m} to (0,1,2,3,...,n} is one-to-one and/or onto. The inputs to your program will be: - an integer m - an integer n, and - a two dimensional boolean array F of size (m+1) x (n+1), where F[ i , j ] = 1 if F(i) = j.

Write a recursive function named multiply that takes two positive integers as parameters and returns the product of those two numbers (the result from multiplying them together). Your program should not use multiplication - it should find the result by using only addition.

Write a function addStrings(string1, string2) that takes in two decimals as strings and returns a string of their sum. *Simply converting strings to numbers and adding them together isn’t acceptable.* The program must be able to handle large decimals. Be sure to touch on these when solving for the solution: Pad the right side Pad the left side Make sure string is same length by putting 0’s where it was missing (be careful w/ decimal points) Make sure to remove...

2 Write a function named equivalentArrays that has two array arguments and returns 1 if the two arrays contain the same values (but not necessarily in the same order), otherwise it returns 0. Your solution must not sort either array or a copy of either array! Also you must not modify either array, i.e., the values in the arrays upon return from the function must be the same as when the function was called. Note that the arrays do not...
