Answer:
1. - Observer
2. - iterator
3. - strategy
4. - composite
5. - decorator
Explanation:
An object contains other objects (elements) and must give access to them for clients, without exposing its internal structure. This is an observation.
The subject-object can generate events as an iterable (iterator) and could use different strategic algorithms to achieve a task. Class objects can be used to aggregate other class objects.
In python, the decorator function mimics the outer function of a nested function, but still maintains the functionality of the second function
Some devices that depend on gravity to function include scales, showers, and satellites, to list a few.
The format for the UPDATE command is the word UPDATE, followed by the name of the table to be updated. The next portion of the command consists of the word <u>SET</u>, followed by the name of the column to be updated, an equals sign, and the new value.
Explanation:
- An Update Query is an action query (SQL statement) that changes a set of records according to criteria you specify.
- The SQL UPDATE Query is used to modify the existing records in a table. You can use the WHERE clause with the UPDATE query to update the selected rows, otherwise all the rows would be affected.
- Update Queries let you modify the values of a field or fields in a table.
<u>UPDATE Syntax
</u>
- UPDATE table_name
- SET column1 = value1, column2 = value2, ...
- WHERE condition;
UPDATE table_name SET column1 = value1, column2 = value2, etc WHERE condition;
- table_name: name of the table
- column1: name of first , second, third column....
- value1: new value for first, second, third column....
- condition: condition to select the rows for which the
- values of columns needs to be updated.

Answer:
The longest codeword that could possibly be for "n" symbol is n-1 bits.
Explanation:
From the given information:
Suppose we are to consider a set of frequencies 
, for which f is a symbol for the length n. Therefore, the longest codeword that could possibly be for "n" symbol is n-1 bits.
However, during the encoding for "n" in conjunction with n-2, then the possibilities for n are; 
We can conclude that the longest codeword that could possibly be for "n" symbol is n-1 bits.
