Functions can be passed as parameters just like other values in ML.For example, consider these function definitions: fun sqaure a = a * a; fun double a = a + a; fun compute (n,f) = f n; The functions square and double take a single int parameter and return an int result.The function compute takes a value n and a function f, and returns the result of calling that function f with n as its parameter.So, compute(3,square) evaluates to 9, and compute(3,double) to 6. * Make another version of quicksort function, but this time of type 'a list * ('a * 'a -> bool) -> 'a list. The second parameter should be a function that performs the role of the <comparision in your origional function. Why would you want to define a function? because it is much more useful than the origional one. For example, suppose you define icmp and rcmp like this: fun icmp (a, b) = a < b; func rcmp ( a : real, b) = a < b; You should now use quick sort(L, icmp) to sort an integer list L, and you could use quicksort(M, rcmp) to sort a real list M. and if you defined: fun ircmp(a,b) = a > b; then you could use quicksort(L, ircmp) to sort the integer list L in reverse order.
Decide what factors are significant in your decision as to which computer to purchase and write them. After you choose the system you would like to buy, recognize which terms refer to hardware and which refer to software.
Describe an algorithm for determining if a given list contains a cycle using only constant additional space. The runtime should be O(N), where N is the (unknown) number of elements in the list. (Hint: use two iterators that advance at different sp..
