# Task
 Mr.Nam has `n` candies, he wants to put one candy in each cell of a table-box. The table-box has `r` rows and `c` columns.

 Each candy was labeled by its cell number. The cell numbers are in range from 1 to N and the direction begins from right to left and from bottom to top.

 Nam wants to know the position of a specific `candy` and which box is holding it.

 The result should be an array and contain exactly 3 elements. The first element is the `label` of the table; The second element is the `row` of the candy; The third element is the `column` of the candy.
 
 If there is no candy with the given number, return `[-1, -1, -1]`.

 Note: 
 
 When the current box is filled up, Nam buys another one. 
 
 The boxes are labeled from `1`.

 Rows and columns are `0`-based numbered from left to right and from top to bottom.
 
# Example

 For `n=6,r=2,c=2,candy=3`, the result should be `[1,0,1]`
 
 the candies will be allocated like this:
```
Box 1
+-----+-----+
|  4  | (3) | --> box 1,row 0, col 1
+-----+-----+
|  2  |  1  |
+-----+-----+
Box 2
+-----+-----+
|  x  |  x  |
+-----+-----+
|  6  | (5) | --> box 2,row 1, col 1
+-----+-----+```
 For `candy = 5(n,r,c same as above)`, the output should be `[2,1,1]`.
 
 For `candy = 7(n,r,c same as above)`, the output should be `[-1,-1,-1]`.
 
 For `n=8,r=4,c=2,candy=3`, the result should be `[1,2,1]` 
```
Box 1
+-----+-----+
|  8  |  7  |
+-----+-----+
|  6  |  5  |
+-----+-----+
|  4  | (3) |--> box 1,row 2, col 1
+-----+-----+
|  2  |  1  |
+-----+-----+
```

# Input/Output


 - `[input]` integer `n`

  The number of candies. 
  
  `0 < n <= 100`


 - `[input]` integer `r`

  The number of rows. 
  
  `0 < r <= 100`


 - `[input]` integer `c`

 The number of columns.

 `0 < c <= 100`


 - `[input]` integer `candy`

 The label of the candy Nam wants to get position of.
 
 `0 < c <= 120`

 - `[output]` an integer array

  Array of 3 elements: a label, a row and a column.
