Function prototyping is a function declaration statement that tells the compiler about the return type of the function and the number as well as type of arguments required by the function at the time of calling it.

Syntax:

return_type function_name( type1 arg1, type 2 arg2, ... );

Advantages of function prototype :

- It helps the compiler in determining whether a function is called correctly or not. Each time when a function is called, its calling statement is compared with its prototype. In case of any mismatch, compiler reports an error.

- A function must be defined before calling it. But prototyping allows a function to be called before defining it.

deleteCharAt() method deletes the character at the specified index location and returns the resulting StringBuffer object.

So after deleting the character at 0 ie 'H', the string returns 'ello' as the output.

In argument[0] = args;, the reference variable arg[0], which was referring to an array with two elements, is reassigned to an array (args) with three elements.
Output:
$ javac main_arguments.java
$ java main_arguments
1 2 3

- Agglomerative Hierarchical clustering method allows the clusters to be read from bottom to top and it follows this approach so that the program always reads from the sub-component first then moves to the parent. Whereas, divisive uses top-bottom approach in which the parent is visited first then the child. 

- Agglomerative hierarchical method consists of objects in which each object creates its own clusters and these clusters are grouped together to create a large cluster. It defines a process of merging that carries on till all the single clusters are merged together into a complete big cluster that will consists of all the objects of child clusters. Whereas, in divisive the parent cluster is divided into smaller cluster and it keeps on dividing till each cluster has a single object to represent.

BRS - Bank Reconciliation Statement

     - Cheques issued by the organization but not yet presented for payment

     - Cheques directly deposited by customers into the bank

     - Bank charges debited by bank

     - Interest credited or some receipts directly collected by bank based on org. request.

     - Some payments directly made by bank based on the organizations request.

So, the statement shows the reasons as what are the reasons for difference in balance.
