When data is deleted from a workbook, it is removed from the cells where it was stored, and the workbook no longer contains the information that was previously in those cells. To explain this process step-by-step:
1. When you delete data from a cell or a range of cells in a workbook, you are essentially erasing the content within those specific locations.
2. The workbook adjusts the remaining data accordingly. For example, if you delete an entire row or column, the remaining rows or columns will shift up or left to fill the gap left by the deleted data.
3. If the deleted data was being used in calculations or formulas within the workbook, these may no longer function properly, resulting in error messages or incorrect results.
4. Once you save the workbook after deleting the data, the changes become permanent. The deleted data is no longer stored within the file, and it cannot be retrieved directly from the workbook itself.
It's important to note that once data has been deleted and the workbook is saved, the only way to recover the deleted data is by using a previously saved version of the workbook, if available, or using specialized data recovery tools. However, these methods are not guaranteed to restore the data successfully. It is always recommended to create backups of important workbooks to prevent the loss of crucial data.

What's the difference between git merge and git rebase?
Git merge creates a new commit that joins the histories of the two branches, while git rebase rewrites the project history by creating new commits based on the latest commit of the source branch.
Git merge takes the changes from one branch and applies them to another, creating a new merge commit that has two parent commits. Git rebase, on the other hand, takes the changes from one branch and replays them on top of another, creating a linear history without merge commits.
This can make the history cleaner and easier to follow, but it can also create conflicts if there are overlapping changes. It's important to understand the differences between these two commands and choose the one that is best for your workflow and project needs.

Given a sequence of Words and the Order of the alphabet. The order of the alphabet is some permutation of lowercase letters. The task is to check whether the given words are sorted lexicographically according to order of alphabet. Return "True" if it is, otherwise "False".
Answer:
def is_sorted(words, order):
# Create a dictionary to map each letter to its position in the order string
order_dict = {order[i]: i for i in range(len(order))}
# Check each pair of adjacent words in the sequence
for i in range(len(words) - 1):
word1 = words[i]
word2 = words[i + 1]
# Compare the two words letter by letter
for j in range(min(len(word1), len(word2))):
if word1[j] != word2[j]:
if order_dict[word1[j]] > order_dict[word2[j]]:
return False
break
else:
if len(word1) > len(word2):
return False
return True
Explanation:
First, we create a dictionary order_dict that maps each letter in the order string to its position in the string. For example, if order = "bcdefghijklmnopqrstuvwxyza", then order_dict will be {'a': 25, 'b': 0, 'c': 1, ..., 'y': 23, 'z': 24}.
Next, we loop over each pair of adjacent words in the words sequence. For each pair of words, we compare them letter by letter.
If we find a pair of letters that are different, we compare their positions in the order string. If the position of the first letter is greater than the position of the second letter, then the words are not sorted lexicographically, and we return False.
If we reach the end of the loop without finding any mismatched letters, we compare the lengths of the two words. If the first word is longer than the second word, then the words are not sorted lexicographically, and we return False.
If we have checked all pairs of adjacent words without finding any problems, then the words are sorted lexicographically according to the order of the alphabet, and we return True.
Here's an example usage of the function:
python
>>> words = ["hello", "hi", "hills"]
>>> order = "hieabfcdgjkmlnopqrstuvwyxz"
>>> is_sorted(words, order)
True
>>> words = ["apple", "banana", "orange"]
>>> order = "abcdefghijklmnopqrstuvwxyz"
>>> is_sorted(words, order)
False

What is difference between Serializable and Parcelable ? Which is best approach in Android ?
Difference
The main difference between Serializable and Parcelable in Android is their purpose and performance. Serializable is a Java interface that enables an object to be converted into a byte stream for storage or transmission purposes, while Parcelable is an Android-specific interface used for the same purpose but is more efficient and faster in Android.
What is the best approach?
The best approach is using Parcelable because:
1. Parcelable is specifically designed for Android, resulting in better performance.
2. Parcelable allows you to explicitly define how an object should be serialized, which can lead to a smaller memory footprint.
3. Parcelable is faster than Serializable, as it doesn't use reflection to identify and serialize fields.
To implement Parcelable in Android, follow these steps:
1. Make your class implement the Parcelable interface.
2. Implement the writeToParcel(Parcel dest, int flags) method to define how the object should be serialized.
3. Create a static final Parcelable.Creator CREATOR field that generates instances of your Parcelable class from a Parcel.
Overall, Parcelable is the recommended approach in Android for passing objects between components, as it offers better performance and efficiency compared to Serializable.

Explain the fundamental differences between the UNIX fork() and Windows CreateProcess() functions.
The fundamental differences between UNIX fork() and Windows CreateProcess() functions are as follows:
1. Purpose: fork() is used to create a new process in UNIX, which is a clone of the parent process with a separate memory space. CreateProcess() in Windows is used to create a new process with a specified executable file to run.
2. Inheritance: In UNIX, fork() duplicates the parent process, inheriting its file descriptors, environment variables, and memory layout. In Windows, CreateProcess() doesn't inherit these attributes directly; instead, it requires explicit configuration during process creation.
3. Memory: fork() shares the same memory layout between parent and child processes initially, with copy-on-write protection. CreateProcess() assigns a completely separate memory space for the new process in Windows.
4. Process ID: fork() returns the child's process ID in the parent process and zero in the child process. CreateProcess() returns a PROCESS_INFORMATION structure containing the new process's handle and process ID.

This order is determined beforehand and is based on the relative importance of the resources. By enforcing this protocol, the system can avoid situations where one process is holding onto a resource that is needed by another process, leading to a deadlock.
By implementing either or both of these protocols, the hold-and-wait condition can be prevented from occurring in a system, leading to more efficient and reliable system performance.
