# Intuition

We need to determine if two strings are "almost equal." The two strings are considered almost equal if:
1. They are already the same.
2. We can make them equal by swapping **exactly two characters**.

# Approach:
1. **Check if they are already equal:** If `s1` is the same as `s2`, return `True`.
2. **Check if lengths match:** If the strings have different lengths, return `False` immediately.
3. **Count mismatches:** Compare each character in `s1` with `s2`. Count how many positions are different between the two strings.
4. **Validate swap:** If two characters differ, check if both strings have the same character frequencies (using `Counter`).
5. **Return result:** If both conditions are met, return `True`, otherwise `False`.

# Complexity
- **Time complexity:** $$O(n)$$  
  We iterate through the strings twice, so it’s linear time.

- **Space complexity:** $$O(n)$$  
  We use extra space to store character counts, which is proportional to the string length.

# Code
```python3 []
class Solution:
    def areAlmostEqual(self, s1: str, s2: str) -> bool:
        if s1 == s2:
            return True
            
        i = 0
        j = 0


        if len(s1) != len(s2):
            return False

        c = 0 
        while i < len(s1) and j <len(s2):
            if s1[i] != s2[j]:
                c += 1
            i+= 1
            j+= 1

        if c == 2 and Counter(s1) == Counter(s2):
            return True
        else:
            return False
