### Problem Statement

On a plotter, the mechanical arm that draws on paper with a pen has a motor that can move it back and forth across the paper sideways. The plotter also has a paper motor, which can move the paper orthogonally to the plotter's arm, which effectively is like moving the pen up and down the paper. The paper is square, and is oriented so its lower edge is parallel to the arm. This allows the plotter to move to any coordinates using the two motors. Both motors can be active simultaneously, and each motor can move the pen up to one pixel per millisecond in relation to the paper (it's possible for a motor to run slower).

Given the list of lines that the plotter must put on the paper, return the minimum time it takes to plot the given lines, in milliseconds. The plotter's pen starts at the coordinates (0,0), and after drawing all the lines, must return to (0,0). Note that the plotter cannot draw partial lines. Each element of lines will be in the form "x1 y1 x2 y2". This represents a line from point (x1,y1) to point (x2,y2). It takes 0 time to lower the pen down on the paper, and to raise it off the paper.

### Definition

 Class: LinePlotter Method: timeToPlot Parameters: String[] Returns: int Method signature: int timeToPlot(String[] lines) (be sure your method is public)

### Notes

-There can be 0-length lines, which are drawn by moving to the designated location, lowering the pen and without moving, raising the pen.

### Constraints

-lines will contain between 1 and 15 elements, inclusive.
-Each element of lines will be of the form "x1 y1 x2 y2", where each value is an integer between 0 and 9999, inclusive.
-There will be no extra leading zeros in any of the numbers in lines.
-There will be no repeated elements in lines. This includes lines which are reversed. For example, if "x1 y1 x2 y2" appears, then "x2 y2 x1 y1" cannot.
-No two lines can intersect at more than one point.

### Examples

0)

 `{"0 1 1 0"}`
`Returns: 3`
 This is a line which draws a diagonal across the bottom corner of the paper. The line can be drawn by first running the arm motor to bring the pen over to (1,0) in 1 millisecond. Then the paper motor can be run simultaneously with the lateral motor to draw the line from (1,0) to (0,1) in one more millisecond. Finally, the paper motor brings the pen back to (0,0) in one more millisecond.
1)

 `{"0 0 5 5", "5 5 0 5", "0 100 0 4"}`
`Returns: 205`
 The best path first draws the line from (0,0) to (5,5). Since both motors can move at top speed, this line takes 5 milliseconds to draw. Without even picking up the pen, we can draw the line from (5,5) to (0,5) in 5 milliseconds. Finally, to draw the final line, we lift the pen, go all the way up to (0,100), and draw the line to (0,4). This adds 95 + 96 = 191 milliseconds. Finally, we lift the pen and move back to (0,0), adding an additional 4 milliseconds. The total time is 5 + 5 + 95 + 96 + 4 = 205 milliseconds.
