+# [2317.Maximum XOR After Operations ][title]
+
+## Description
+You are given a **0-indexed** integer array `nums`. In one operation, select **any** non-negative integer `x` and an index `i`, then **update** `nums[i]` to be equal to `nums[i] AND (nums[i] XOR x)`.
+
+Note that `AND` is the bitwise AND operation and `XOR` is the bitwise XOR operation.
+
+Return the **maximum** possible bitwise XOR of all elements of `nums` after applying the operation **any number** of times.
+
+**Example 1:**
+
+```
+Input: nums = [3,2,4,6]
+Output: 7
+Explanation: Apply the operation with x = 4 and i = 3, num[3] = 6 AND (6 XOR 4) = 6 AND 2 = 2.
+Now, nums = [3, 2, 4, 2] and the bitwise XOR of all the elements = 3 XOR 2 XOR 4 XOR 2 = 7.
+It can be shown that 7 is the maximum possible bitwise XOR.
+Note that other operations may be used to achieve a bitwise XOR of 7.
+```
+
+**Example 2:**
+
+```
+Input: nums = [1,2,3,9,2]
+Output: 11
+Explanation: Apply the operation zero times.
+The bitwise XOR of all the elements = 1 XOR 2 XOR 3 XOR 9 XOR 2 = 11.
+It can be shown that 11 is the maximum possible bitwise XOR.
+```
