Answer:
True
Explanation:
The notation O(n), pronounced big-O of n is an indication of the complexity of an algorithm. It is an indication of the relationship between the processing time and size of input
So O(n) means the time - input relationship is linear. If it takes x time units to process an input of size y then it will take 5x units to process an input of size 5y
O(1) means the time to process is independent of size. It is always constant. For example in computer algorithms, the time to access a value in an array of values is independent of the size of the array because arrays are indexed and access time for any element of the array is the same
O(n²) means that the time taken varies as the square of the input size

The ALU (Arithmetic Logic Unit), located in the system unit, is the component of the computer utilized for calculations and comparisons.
Describe ALU.Arithmetic-logic unit (ALU) definition Arithmetic and logic operations are performed on the operands in computing instruction words by an arithmetic-logic unit, a component of a central processing unit. Some processors separate the ALU into an arithmetic logic unit (AU) and an arithmetic logic (LU).
What are the primary purposes of an ALU?Simple multiplication, division, addition, subtraction, addition, and logic operations like OR and AND are all performed by the ALU. The data and instructions for the program are stored in memory. Data and instructions are retrieved by the control unit from memory.

what do we generally avoid in a many-to-many junction table?
a. two foreign keys
b. an auto increment primary key column
c. data items specific to the many-to-many relationship
d. a logical key
Not An AUTOINCREMENT primary key column, Data items specific to the many-to-many relationship. When numerous records in one table are linked to several records in another table, this is known as a many-to-many relationship.
What is many to many junction?
When numerous records in one table are linked to several records in another table, this is known as a many-to-many relationship.
The simplest method is to utilize a Junction Table when you need to create a many-to-many link between two or more tables. By referring to the main keys of each data table, a junction table in a database, also known as a bridge table or associative table, connects the databases.
A many-to-many relationship, or type of cardinality, is used in systems analysis to describe the relationship between two entities, such as A and B, where A may have a parent instance for whom there are many offspring in B and vice versa.

how do you fill different data into different cells at a time in Excel
The way that you fill different data into different cells at a time in Excel are:
Click on one or a lot of cells that you want to make use of as the basis that is needed for filling additional cells. For a set such as 1, 2, 3, 4, 5..., make sure to type 1 and 2 into the 1st two cells. Then pull the fill handle .If required, select Auto Fill Options. and select the option you want.How do you make a group of cells auto-fill?The first thing to do is to place the mouse pointer over the cell's bottom right corner and hold it there until a black + symbol appears. Drag the + symbol over the cells you wish to fill in while clicking and holding down the left mouse button. Additionally, the AutoFill tool rightly fills up the series for you.
Note that Excel data entering can be automated and this can be done by: On the Data tab, select "Data Validation," then click "Data Validation." In the Allow box, select "List." Enter your list items in the Source box, separating them with commas. To add the list, click "OK." If you wish to copy the list along the column, use the Fill Handle.

The answers are input and output, respectively.
Explanation:
you have a 10vdg source available design a voltage divider ciruit that has 2 vdc , 5vdc , and 8 vdc available the total circuit current is to be 2mA
If you try to divide 10V in three voltages, the sum of the three voltages must be equal to the total voltage source, in this case 10V. Having said this, 2 + 5 + 8 = 15V, and your source is only 10V. So you can see is not feasible. You can, for example, have 2V, 5V and 3V, and the sum is equal to 10V. Before designing the circuit, i.e, choosing the resistors, you need to understand this. Otherwise, I suggest you to review the voltage divider theory.
For instance, see IMG2 in my previous post. If we were to design a single voltage divider for the 5VDC, i.e, 50% of the 10V source, you generally choose R1 = R2., and that would be the design equation.

Writting the code:lst = ["H", "wor", "o w"]
s = "Hello world"
