**Exercise 11: Working with Arrays**
**Given the array M below, answer the following questions:**
\[
\begin{array}{ccccc}
1 & 2 & 7 & 6 & 5 \\
2 & 9 & 6 & 4 & 9 \\
8 & 6 & 3 & 2 & 1 \\
3 & 0 & 1 & 3 & 6 \\
\end{array}
\]
**Questions:**
a. Write one line of code that extracts the last two rows, and all the columns of M:
b. Write one line of code that extracts all the rows, and the odd columns of M:
c. Write one line of code that extracts rows 1, 2, and 4, and all the even columns of M and stores it in the variable C:
d. Write one line of code that extracts the even rows and columns 3 and 4 of M:
---
**Explanation of the Array:**
- The array M is a 4x5 matrix. Each row of the matrix is indexed from top to bottom starting at 1.
- Column elements are indexed from left to right starting at 1.
- Users are asked to write code to extract specific subarrays based on row and column criteria provided in each sub-question.
---
**Graphical Explanation:**
- The grid contains numbers arranged in rows and columns.
- Participants need to understand indexing to extract specific data correctly, emphasizing the use of slicing or indexing in a programming context (unspecified language).
