I know that an API is called a set of functions used to call something, and a library is a collection of classes, but what is actually API in package like Java.lang? I can connect to a class like System without using any API here, so why we say as J2SE API rather than J2SE packages? ...

Can you suggest some good Javascript assignments/homework to C programmers, who are not much familiar with Javascript? They are strong in C, hence basic Javascript. I need few JS related assignments which I can assign to them, to help them understand Web-Dev and Prototype concepts. I'm not looking for the tutorials which they need to ...

A binary tree can be encoded using two functions l and r such that for a node n, l(n) give the left child of n, r(n) give the right child of n. A branch of a tree is a path from the root to a leaf, the length of a branch to a particular leaf is the number of arcs on the path from the root to that leaf. Let MinBranch(l,r,x) be a simple ...

Write tertiary search program. Notes: Tertiary search is similar to binary search. In binary search we consider two parts of the array and select one part as the next search space. In tertiary search we consider the array in 3 equal parts. For this, we take two "middle" indices, middle1 and middle2 respectively at 1/3 and 2/3 of the arra...
Before the advent of inkjet and laser printers, straight line drawings used to be plotted by coloured pens on large sheets of paper: the pens moved very slowly so this was a time-consuming process. Since time is money, it was important to draw figures in an optimal way, using minimum time. you will implement an A* search procedure for t...
I'm trying to implement the following with OCaml for a homework assignment: g(n) = y if n = x else f(n) so, for example if f(n) = n+1, x = 7, y=42, then g(1) = 2, but g(7) = 42 I've got: # let update f x y = f(x) = y;; val update : ('a -> 'b) -> 'a -> 'b -> bool = < fun> but I just don't know the syntax I should use in order to ...
