To solve a palindrome, compare the string with its reverse. To reverse a string, iterate through it in reverse order.

• Iterate through the string in reverse order to create the reversed string.

• Compare the original string with the reversed string to check if it is a palindrome.

• Handle cases where the input string is empty or null.

Reverse a string

• Use a loop to iterate through the characters of the string

• Swap the characters from start to end to reverse the string

• Return the reversed string

Use nested loops to iterate through each array and each element in a jagged array of strings.

• Use a nested loop to iterate through each array in the jagged array

• Within the nested loop, iterate through each element in the current array

• Access each element using the indices of the arrays

Static value is a value that remains constant and does not change.

• Static value does not vary or fluctuate.

• It remains the same regardless of external factors.

• Examples include mathematical constants like pi (π) or physical constants like the speed of light.

Debugging is the process of identifying and fixing errors in code to ensure it runs smoothly.

• Use print statements to track the flow of the program and identify where the error occurs

• Utilize debugging tools like breakpoints to pause the program at specific points and inspect variables

• Step through the code line by line to understand the execution flow and pinpoint the issue

• Check for syntax errors, logical errors, and run
