【第三轮】7.24-7.31 CareerCup 5.8

5.8 A monochrome screen is stored as a single array of bytes, allowing eight consecutive pixels to be stored in one byte. The screen has width w, where w is divisible by 8 (that is, no byte will be split across rows). The height of the screen, of course, can be derived from the length of the array and the width. Implement a function drawHorizontalLine(byte[] screen, int width, intxl, intx2, inty) which draws a horizontal [/size]line from (x 1, y) to (x2, y).
