Answer: You would need two loops to iterate through both dimensions

Explanation:

matrix = [[1,2,3,4,5],

[6,7,8,9,10],

[11,12,13,14,15]]

for rows in matrix:

for numbers in rows:

print(numbers)

The first loop cycles through all the immediate subjects in it, which are the three lists. The second loop calls the for loop variable and iterates through each individual subject because they are lists. So the first loop iterates through the 1st dimension (the lists) and the seconds loop iterates through the 2nd dimension (the numbers in the lists).

what is the difference between recursion and iteration in C, and their advantages and disadvantages? ...?

madam [21]

I think both recursive and iteration are different programming approaches which have their own benefits and drawbacks .

<span><span>Recursive approach: In recursive approach the function calls itself until the condition is met. And it is slower than iteration,which means it uses more memory than iteration. recursion is like a selection structure, and which makes code smaller and clean. And a function partially defined by itself. Here tracing the code will be more difficult in the case large programs.</span><span><span>Iterative approach: </span>Iterative approach is a repetition process until the condition fails,here loops are used such as for ,while etc. Here code may be longer but it is faster than recursive. And it consumes less memory compared to recursive approach.If the loop condition is always true in such cases it will be an infinite loop.</span></span>

If a schema is not given, you may assume a table structure that makes sense in the context of the question. (using sql queries)

adell [148]

Answer:

The correct query is;

select * from EMPLOYEE where Employee_Name = 'JOE' or Employee_Name = 'Joe' or Employee_Name = 'joe';

where EMPLOYEE refer to the table name and type attribute name is Employee_Name

Explanation:

Here, the first thing we will do is to assume the name of the table.

Let’s assume the table name is EMPLOYEE, where the column i.e attribute from which we will be extracting our information is Employee_Name

The correct query to get the piece of information we are looking for will be;
