Reversing a string involves rearranging its characters in the opposite order, which can be done using various methods in programming.
Use built-in functions: In Python, use slicing: `reversed_string = original_string[::-1]`.
Iterative approach: Loop through the string from the end to the beginning and build a new string.
Using recursion: Define a function that calls itself with a substring until it reaches the base case.

Find the maximum sum of a contiguous subarray within a one-dimensional array of numbers.
Use Kadane's Algorithm for an efficient O(n) solution.
Initialize two variables: max_so_far and max_ending_here.
Iterate through the array, updating max_ending_here and max_so_far.
Example: For array [-2,1,-3,4,-1,2,1,-5,4], max subarray sum is 6 (from subarray [4,-1,2,1]).
Edge case: For an empty array, return 0.

Response codes in API indicate the status of a request
Response codes are standardized codes sent by a server in response to a client's request
Common response codes include 200 (OK), 404 (Not Found), and 500 (Internal Server Error)
