441 - Arranging Coins\. Easy You have `n` coins and you want to build a staircase with these coins. The staircase consists of `k` rows where the ith row has exactly `i` coins. The last row of the staircase **may be** incomplete. Given the integer `n`, return _the number of **complete rows** of the staircase you will build_. **Example 1:** ![](https://assets.leetcode.com/uploads/2021/04/09/arrangecoins1-grid.jpg) **Input:** n = 5 **Output:** 2 **Explanation:** Because the 3rd row is incomplete, we return 2. **Example 2:** ![](https://assets.leetcode.com/uploads/2021/04/09/arrangecoins2-grid.jpg) **Input:** n = 8 **Output:** 3 **Explanation:** Because the 4th row is incomplete, we return 3. **Constraints:** * 1 <= n <= 231 - 1
