## What is Data Structures and Algorithms?
1210

1311
Data Structures and Algorithms are the building blocks of computer science. Data structures are a way of organizing and storing data in a computer so that it can be accessed and modified efficiently. Algorithms are a set of instructions that are used to perform a specific task. Data structures and algorithms are used to solve complex problems in computer science and software development.

## Solution for Best Time to Buy and Sell Stock Problem

### Intuition
55+
5756
The intuition behind the solution is to treat each letter as a digit in a base-26 number system, where 'A' represents 1, 'B' represents 2, ..., 'Z' represents 26. The solution then iterates through each character in the column title, calculates the numeric value of the corresponding letter, and accumulates the result by considering the positional weight of each letter.
5857

5958
### Approach
6059

6160
- Initialize variables x and ans to keep track of the positional weight and the accumulated result, respectively.
6261
- Iterate through each character s in the columnTitle.
6362
- Convert the character s to its numeric representation by using the ord function (ASCII value) and subtracting 64 (since 'A' corresponds to 65 in ASCII).
64-
- Update the result (ans) by adding the product of the numeric representation, positional weight (26**x), and decrease the positional weight x by 1.
63+
- Update the result (ans) by adding the product of the numeric representation, positional weight (26\*\*x), and decrease the positional weight x by 1.
6564
- Repeat this process for each character in the column title.
6665
- Return the final accumulated result.
