Problem Explanation

Explanation

To fix the product name format, we need to ensure that the name is capitalized and does not contain any leading or trailing spaces. We can achieve this by first converting the name to lowercase, then capitalizing the first letter, and finally removing any leading or trailing spaces.

Convert the product name to lowercase.
Capitalize the first letter of the name.
Remove any leading or trailing spaces.

Time complexity: O(n) where n is the length of the product name. Space complexity: O(1)

Solution Code

class Solution {
    public String fixProductName(String name) {
        if (name == null || name.length() == 0) {
            return "";
        }
        
        // Convert name to lowercase
        name = name.toLowerCase();
        
        // Capitalize first letter
        name = name.substring(0, 1).toUpperCase() + name.substring(1);
        
        // Remove leading and trailing spaces
        name = name.trim();
        
        return name;
    }
}
