WebMethods are functions that belongs to the class. There are two ways to define functions that belongs to a class: Inside class definition. Outside class definition. In the following example, we define a function inside the class, and we name it " myMethod ". Webusing comparisons to locate keys. The best known method is called hashing. Hashing and its variants support all the dictionary operations in O(1) (i.e. constant) expected time. Hashing is considered so good, that in contexts where just these operations are being performed, hashing is the method of choice.
