Problem

Have some eggplant instead...

Last year, NLCS Jeju fended off a campaign by students who opposed "Parmesan-breaded fried beef" (hereafter "Parmesan beef") and launched a new menu item, "Parmesan-breaded fried beef kimbap" (hereafter "Parmesan beef kimbap").

The students, however, would rather eat fresh eggplant than Parmesan beef! So they plan to buy eggplant and swap out all the Parmesan beef in today's lunch Parmesan beef kimbap for eggplant. To do this, they need to work out how many grams of eggplant to buy.

  • Each roll of Parmesan beef kimbap contains exactly NN grams of Parmesan beef.
  • The school used MM grams of Parmesan beef to make today's kimbap.
  • The number of rolls the school makes is an integer. For example, the school cannot make 2.5 rolls.
  • Each roll of Parmesan beef kimbap must have exactly KK grams of eggplant swapped in for its Parmesan beef.

Find the minimum number of grams of eggplant the students must buy to replace all the Parmesan beef the school made into eggplant.

Input

The first line contains the integer NN, the grams of Parmesan beef in one roll of Parmesan beef kimbap.

The second line contains the integer MM, the grams of Parmesan beef the school used.

The third line contains the integer KK, the grams of eggplant needed for one roll.

Output

On one line, print the minimum number of grams of eggplant the students must buy.

Constraints

1≤N,M,K≤1 0001 \le N,M,K \le 1\,000

MM is a multiple of NN.
