Is anyone know how to do this program? This program need to print all the stage, but only print the number. For example, stage 1- only print 4 1 3 2 16 9 10 14 8 7
 input>  4 1 3 2 16 9 10 14 8 7
 stage1:  4 1 3 2 16 9 10 14 8 7
 stage 2:  4 1 3 2 16 * 9 10 14 8 7
 stage 3:  4 1 3 2 * 16 9 10 14 8 7
 stage 4:  4 1 3 * 14 16 9 10 2 8 7
 stage 5:  4 1 * 10 14 16 9 3 2 8 7
 stage 6:  4 * 16 10 14 7 9 3 2 8 1
 stage 7:  16 14 10 8 7 9 3 2 4 1
 stage  8:  14 8 10 4 7 9 3 2 1 * 16
 stage 9:  10 8 9 4 7 1 3 2 * 14 16
stage 10:  9 8 3 4 7 1 2 * 10 14 16
stage 11:  8 7 3 4 2 1 * 9 10 14 16
stage 12:  7 4 3 1 2 * 8 9 10 14 16
stage 13:  4 2 3 1 * 7 8 9 10 14 16
stage 14:  3 2 1 * 4 7 8 9 10 14 16
stage 15:  2 1 * 3 4 7 8 9 10 14 16
stage 16:  1 * 2 3 4 7 8 9 10 14 16
Final stage 17:  1 2 3 4 7 8 9 10 14 16
Thank you
