Difficulty—

Fennec is fighting with $N$ monsters. The _health_ of the $i$\-th monster is $H_i$. Fennec can do the following two actions: * Attack: Fennec chooses one monster. That monster's health will decrease by $1$. * Special Move: Fennec chooses one monster. That monster's health will become $0$. There is no way other than Attack and Special Move to decrease the monsters' health. Fennec wins when all the monsters' healths become $0$ or below. Find the minimum number of times Fennec needs to do Attack (not counting Special Move) before winning when she can use Special Move at most $K$ times. ## Constraints * $1 \leq N \leq 2 \times 10^5$ * $0 \leq K \leq 2 \times 10^5$ * $1 \leq H_i \leq 10^9$ * All values in input are integers. ## Input Input is given from Standard Input in the following format: $N$ $K$ $H_1$ $...$ $H_N$ [samples]
