Little Bobby loves chocolate. He frequently goes to his favorite 5 & 10 store, Penny Auntie, to buy them. They are having a promotion at Penny Auntie. If Bobby saves enough wrappers, he can turn them in for a free chocolate.

**Example**

n=15 c=3 m=2

He has 15 to spend, bars cost 3, and he can turn in 2 wrappers to receive another bar. Initially, he buys 5 bars and has 5 wrappers after eating them. He turns in 4 of them, leaving him with 1, for 2 more bars. After eating those two, he has 3 wrappers, turns in 2 leaving him with 1 wrapper and his new bar. Once he eats that one, he has wrappers and turns them in for another bar. After eating that one, he only has 1 wrapper, and his feast ends. Overall, he has eaten 5+2+1+1=9 bars.

**Function Description**

Complete the chocolateFeast function in the editor below.

chocolateFeast has the following parameter(s):

int n: Bobby’s initial amount of money

int c: the cost of a chocolate bar

int m: the number of wrappers he can turn in for a free bar

Returns

int: the number of chocolates Bobby can eat after taking full advantage of the promotion

Note: Little Bobby will always turn in his wrappers if he has enough to get a free chocolate.

**Input Format**

The first line contains an integer,t , the number of test cases to analyze.

Each of the next t lines contains three space-separated integers: n, c, and m. They represent money to spend, cost of a chocolate, and the number of wrappers he can turn in for a free chocolate.

**Sample Input**

STDIN Function ----- -------- 3 t = 3 (test cases) 10 2 5 n = 10, c = 2, m = 5 (first test case) 12 4 4 n = 12, c = 4, m = 4 (second test case) 6 2 2 n = 6, c = 2, m = 2 (third test case)

**Sample Output**

6 3 5
