Which of the following is an example of a scenario where deletion in a 1D array is commonly used?

One common scenario where deletion in a 1D array is used is in data manipulation. For example, you have a list of student names in an array and you need to delete a student who has withdrawn from the course. Here are the steps you would follow:

1. First, you would search the array to find the index of the student's name you want to delete. This can be done using a simple for loop that iterates over the array.

2. Once you have the index, you would shift all the elements to the right of the deleted element to the left by one position. This can also be done using a for loop that starts from the index of the deleted element and ends at the last index of the array.

3. Finally, you would decrease the size of the array by one. This can be done by keeping a separate variable that keeps track of the size of the array. When an element is deleted, you would decrease this variable by one.

This is a simple example, but deletion in a 1D array is used in many other scenarios in computer programming, such as in sorting algorithms, data processing, etc.
