Example Question:

Coding

Bobby has to do *n* chores today. *i*-th chore takes a[i] unit of time to complete. It is guaranteed that for every i, the condition *a[i] *>= *a[i]*-1 is met, so the sequence is sorted.

Also, Bobby can work hard on some chores. He can choose no more than *k* chores and do each in *x* units of time instead of *a[i]*.

Bobby is very responsible, so he has to do all *n* chores, and now he wants to know the minimum time he needs to do everything. Bobby cannot do two chores simultaneously.

k = 2, x = 2 and a = [4, 6, 7, 10]

Since two chores, 7 and 10, can be done in 2 units of time, thus 2+2+4+6 = 14
