+# Remove Element Function
+
+This repository contains a C++ implementation of the `removeElement` function, which removes all occurrences of a specified value from a vector and returns the new length of the vector.
+
+## Function Explanation
+
+- **Function Name**: `removeElement`
+- **Parameters**:
+  - `std::vector<int>& nums`: The input vector of integers.
+  - `int val`: The value to be removed from the vector.
+- **Return Type**: `int`
+  - The function returns the new length of the vector after removing all instances of `val`.
+
+### Algorithm
+The function iterates through the vector and copies each element that is not equal to `val` to the beginning of the vector. It uses a pointer `k` to keep track of the position where the next non-val element should be placed. At the end of the iteration, `k` will be the length of the new vector with all instances of `val` removed.
+
+## Usage
+
+To use this function, include it in your C++ project and call `removeElement` by passing the vector and the value to be removed.
+
+## Example
+
+```cpp
+std::vector<int> nums = {3, 2, 2, 3};
+int val = 3;
+solution sol;
+int newLength = sol.removeElement(nums, val);
+// The result will be `newLength = 2`, and `nums` will be modified to {2, 2}.
