200 in.dat positive integer in the file, and each having a number average between 1000-9999. ReadDat function () 200 which reads the number aa stored in the array. Please prepare function jsSort (), the function is a function of: the size requirements per the number of three in descending order, and then taken to meet this condition before the number 10 are sequentially stored in the array b, after if the three values are equal, as was originally values in ascending order. After calling the function WriteDat () output the results to a file out.dat in bb.
Example: Before treatment 9012 5,099,601,270,258,088
After treatment 8088 7025 6012 9012 5099
