The problem is asking to determine if a given string is a palindrome or not. A palindrome is a word, phrase, number, or other sequences of characters that reads the same forward or backward, ignoring spaces, punctuation, and capitalization.

Here are the steps to solve this problem:

1. Convert all the characters in the string to lowercase. This can be done using the `lower()` function in Python.

2. Remove all non-alphanumeric characters from the string. This can be done using the `isalnum()` function in Python in a list comprehension or a for loop.

3. Check if the string is the same when read forward and backward. This can be done by comparing the string with its reverse, which can be obtained using slicing in Python.

Here is a Python solution for the problem:

```python
def isPalindrome(s):
s = ''.join(ch for ch in s if ch.isalnum()).lower()
return s == s[::-1]
```

In this function, the `join()` function is used to concatenate all the alphanumeric characters in the string `s` after converting them to lowercase. The `[::-1]` slice is used to obtain the reverse of the string. The function returns `True` if the string is the same as its reverse, and `False` otherwise.

For example, if the input is "A man, a plan, a canal: Panama", the function will return `True`. If the input is "race a car", the function will return `False`. If the input is " ", the function will return `True` because an empty string is considered a palindrome.
