Hi, Can you please clarify what’s the extra space used for? What is the purpose of having replace(" “,”")?

Hi @Narayana_Sarma !!
The replace(" ", "") part removes spaces from the original string s so that the comparison of the modified string with its reverse is accurate. It ensures that spaces are not considered when determining if the string is a palindrome.
I hope it helps. Happy Learning
