The original idea is to use a for loop, to judge whether an array of strings and a contrast in front of the same (so to sort) first, if not the same, change color,
There are two problems:
1. How do you write statements inside the for loop change X3 [I + 1] color color
2. Because the number of strings is unknown, can random display colors or recycled,
