# Intuition
The problem requires checking if one string can be transformed into another by swapping characters at specific positions. Since we can swap indices (0,2) and (1,3), we need to verify if these swaps can make the two strings equal.

# Approach
1. Convert the first string into a character array for easy manipulation.
2. Iterate over the first two positions and swap them with their corresponding indices (0 ↔ 2 and 1 ↔ 3) if needed.
3. After each swap, check if the modified array matches the second string.
4. If a match is found, return `true`; otherwise, continue checking.
5. If no valid transformation is possible, return `false`.

- Space complexity: **O(n)** 
# Code
```java []
class Solution {
    public boolean canBeEqual(String s1, String s2) {
        if (s1.length() != s2.length()) {
            return false;
        }

        char[] arr = s1.toCharArray();
        int j;

        for (int i = 0; i < arr.length - 2; i++) {
            j = i + 2;
            if (arr[i] != s2.charAt(i)) {
                char temp = arr[i];
                arr[i] = arr[j];
                arr[j] = temp;
            }

            if (new String(arr).equals(s2)) {
                return true;
            }
        }
        return false;
    }
}
