Ada is an investor in a very unstable and high-risk business: NlogNintendo shares. However, because she has great sympathy for the beautiful-horizontina company, Ada continues to invest anyway.
However, instability sometimes makes it difficult for her to do her long-term portfolio planning. In order to help her, she has hired you to make a program that predicts the value of NlogNintendo. Ada has registered that on D day, a stock NlogNintendo was worth I real. Besides, at the beginning of even days, the stock price rises X reais compared to the price at the end of the previous day. On odd days, the stock price already starts with a real X value below the value at the end of the day. And now? Can you help her know what the stock price will be in F days?
Input
The input is composed of a line containing 4 integers separated by space: D (1 ≤ D ≤ 365) (the day Ada registered the price of the NlogNintendo stock), I (X ≤ I ≤ 1000) (the initial price recorded Of the stock), X (1 ≤ X ≤ I) (the daily stock price change) and F (1 ≤ F ≤ 365) (the number of days in the future that your program should predict the share price).
Output
The output should contain a line with a single integer: the expected price of the F share days after the day the initial price was recorded.
