Insertion sort is a simple sorting algorithm that builds the final sorted array one item at a time.
Start with the second element and compare it with the first element, swap if necessary
Move to the third element and compare it with the second and first element, swap if necessary
Repeat until all elements are sorted
Quick Sort is a sorting algorithm that uses divide and conquer approach to sort elements in an array.
It is a recursive algorithm
It selects a pivot element and partitions the array around the pivot
It has an average time complexity of O(nlogn)
It is widely used in practice due to its efficiency
Binary search is a search algorithm that finds the position of a target value within a sorted array.
It works by repeatedly dividing in half the portion of the array that could contain the target value.
It has a time complexity of O(log n).
It is more efficient than linear search for large arrays.
Example: Searching for the number 7 in the sorted array [1, 3, 4, 5, 7, 9, 10] would return index 4.

Data can be structured (organized in a specific way) or unstructured (not organized).
Preprocessed data is data that has been cleaned, transformed, and organized for analysis or modeling.
Preprocessed data is often used in machine learning and data analysis to improve the accuracy and efficiency of models.
Common preprocessing steps include removing missing values, scaling features, and encoding categorical variables.
Examples of preprocessing techniques include normalization, standardization, one-hot enco

Specify the columns you want to copy from each table in the SELECT statement.
Make sure the columns in the SELECT statement match the columns in the 3rd table where you are pasting the data.
Reverse a string using any programming language
Use built-in functions like reverse() or slice() in languages like Python or JavaScript
Iterate through the string in reverse order and append each character to a new string
Use a stack data structure to push each character onto the stack and then pop them off to reverse the string
