"""
    In LOL world, there is a hero called Teemo and his attacking can make his 
    enemy Ashe be in poisoned condition. Now, given the Teemo's attacking 
    ascending time series towards Ashe and the poisoning time duration per 
    Teemo's attacking, you need to output the total time that Ashe is in 
    poisoned condition.
    You may assume that Teemo attacks at the very beginning of a specific time 
    point, and makes Ashe be in poisoned condition immediately.

    Example:
    Input: [1,4], 2
    Output: 4
    Explanation: At time point 1, Teemo starts attacking Ashe and makes Ashe be 
                 poisoned immediately. 
                 This poisoned status will last 2 seconds until the end of time 
                 point 2. 
                 And at time point 4, Teemo attacks Ashe again, and causes Ashe 
                 to be in poisoned status for another 2 seconds. 
                 So you finally need to output 4.

    Example:
    Input: [1,2], 2
    Output: 3
    Explanation: At time point 1, Teemo starts attacking Ashe and makes Ashe be 
                 poisoned. 
                 This poisoned status will last 2 seconds until the end of time 
                 point 2. 
                 However, at the beginning of time point 2, Teemo attacks Ashe 
                 again who is already in poisoned status. 
                 Since the poisoned status won't add up together, though the 
                 second poisoning attack will still work at time point 2, it 
                 will stop at the end of time point 3. 
                 So you finally need to output 3.

    Note:
        1. You may assume the length of given time series array won't exceed 
           10000.
        2. You may assume the numbers in the Teemo's attacking time series and 
           his poisoning time duration per attacking are non-negative integers, 
           which won't exceed 10,000,000.
