    495 - Teemo Attacking\. Easy Our hero Teemo is attacking an enemy Ashe with poison attacks! When Teemo attacks Ashe, Ashe gets poisoned for a exactly `duration` seconds. More formally, an attack at second `t` will mean Ashe is poisoned during the **inclusive** time interval `[t, t + duration - 1]`. If Teemo attacks again **before** the poison effect ends, the timer for it is **reset** , and the poison effect will end `duration` seconds after the new attack. You are given a **non-decreasing** integer array `timeSeries`, where `timeSeries[i]` denotes that Teemo attacks Ashe at second `timeSeries[i]`, and an integer `duration`. Return _the **total** number of seconds that Ashe is poisoned_. **Example 1:** **Input:** timeSeries = [1,4], duration = 2 **Output:** 4 **Explanation:** Teemo's attacks on Ashe go as follows: - At second 1, Teemo attacks, and Ashe is poisoned for seconds 1 and 2. - At second 4, Teemo attacks, and Ashe is poisoned for seconds 4 and 5. Ashe is poisoned for seconds 1, 2, 4, and 5, which is 4 seconds in total. **Example 2:** **Input:** timeSeries = [1,2], duration = 2 **Output:** 3 **Explanation:** Teemo's attacks on Ashe go as follows: - At second 1, Teemo attacks, and Ashe is poisoned for seconds 1 and 2. - At second 2 however, Teemo attacks again and resets the poison timer. Ashe is poisoned for seconds 2 and 3. Ashe is poisoned for seconds 1, 2, and 3, which is 3 seconds in total. **Constraints:** * 1 <= timeSeries.length <= 104 * 0 <= timeSeries[i], duration <= 107 * `timeSeries` is sorted in **non-decreasing** order.
