    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.
