-### Solution 1
+### Solution 1: Hash Table
+
+First, we use a hash table $d$ to record the index of each number in the array `nums`. Then, we iterate through the operation array `operations`. For each operation $[a, b]$, we replace the number at index $d[a]$ in `nums` with $b$, and update the index of $b$ in $d$ to $d[a]$.
+
+Finally, we return `nums`.
+
+The time complexity is $O(n + m)$, and the space complexity is $O(n)$. Here, $n$ and $m$ are the lengths of the arrays `nums` and `operations`, respectively.

-### Solution 1
+### Solution 1: Left and Right Stacks
+
+We can use two stacks, `left` and `right`, where the `left` stack stores the characters to the left of the cursor, and the `right` stack stores the characters to the right of the cursor.
+
+-   When the `addText` method is called, we push the characters from `text` onto the `left` stack one by one. The time complexity is $O(|\text{text}|)$.
+-   When the `deleteText` method is called, we pop characters from the `left` stack up to $k$ times. The time complexity is $O(k)$.
+-   When the `cursorLeft` method is called, we pop characters from the `left` stack up to $k$ times, then push the popped characters onto the `right` stack, and finally return up to $10$ characters from the `left` stack. The time complexity is $O(k)$.
+-   When the `cursorRight` method is called, we pop characters from the `right` stack up to $k$ times, then push the popped characters onto the `left` stack, and finally return up to $10$ characters from the `left` stack. The time complexity is $O(k)$.
