... space in memory) . Example 3.2: Much of the syntax in modern programming languages is defined in a recursive way. For example, we can define an argument list in Java using the following notation: ... • Calling a method • Performing an arithmetic operation (for example, adding two numbers) • Comparing two numbers • Indexing into an array • Following an object reference • Returning from ... for inserting an element at the beginning of a singly linked list. Assume that the list does not have a sentinel header node, and instead uses a variable head to reference the first node in...

This generic interface specifies that objects of arbitrary object types can be inserted into the ... vector, using an older term). Since our index definition is more consistent with the way arrays are indexed in Java and other programming languages (such as C and C++), we will be referring to ... return types. Such methods could provide significant speedups over index-based methods, because finding the index of an element in a linked list requires searching through the list incrementally...
