C. The winner is ...time limit per test: 1 secоndmemоry limit per test: 256 megаbytes The System fоr Colluding Polls (SCP) wаs secretly creаted by Swifties to make sure their favorite singer wins as many awards as she deserves: all of them! To avoid being detected, they use some clever insights. The system submits a limited number of votes per second, and the number of votes in consecutive seconds can vary by at most n units. Unfortunately, they forgot to store how many votes they submitted to a particular poll. But they know what is the number of votes submitted by the system in the first second and the last second, and the total number of seconds the system was running. Can you estimate what would be the maximum number of votes submitted in this period? Input The first line of the input contains two integers a and b (1≤a,b≤100) — the number of votes in the first second and in the last second, respectively. The second line of the input contains two integers t and n (2≤t≤100,0≤n≤10) — the total number of seconds the system was running and the maximum difference in the number of votes in consecutive seconds, respectively. It is guaranteed that there is a way to change the number of votes from a to b within t seconds with changes of at most n. Output Print the maximum number of votes that could have been submitted. Examples Input #1 Output #1 5 64 2 26 Note: The sequence that maximizes the number of votes looks like this: 5, 7, 8, 6. Input #2 Output #2 10 1010 0 100
