  1. 3D Puzzle Assignment #1 Programming Language, Spring 2003

  2. 3D Puzzle • Characteristics • Consist of • 4ⅹ4ⅹ4 frame • Contains • 63 small cells of equal size • 1 empty position that was the same size as a small cell • A unique number of integer was printed on each small cell • Empty position is marked with ‘$’

  3. Making out a Puzzle • Puzzle • Solving a puzzle • Make the frame display the numbers in order • Operation • Small cell can be moved into empty position • If it were immediately to the right, to the left, in the front, in the rear, above, or below the empty position

  4. Assignment • Objectives • Slide cells into the empty position so that the frame displays the numbers in order • Requirements • Input initial puzzle from file • Show current frame status • Can slide cell into the empty position • by command line input • by sliding-sequence file • Can output complete solution of sliding-sequence into file

  5. Input Convention • Command • Sliding operations • 1 : The square above the empty position moves • 2 : The square below the empty position moves • 3 : The square to the left of the empty position moves • 4 : The square to the right of the empty position moves • 5 : The square in the front of the empty position moves • 6 : The square in the rear of the empty position moves

  6. Source Code • puzzle.c • Input initial puzzle file • Get file name by program argument • $>./puzzle puzzle.in • Show current frame status • Command line input • Input ‘1~6’ command to slide cell • File input • Input ‘1~6’ command from sliding-sequence file • Each line contains maximum 10 command • Output complete solution • Output complete sliding-sequence solution into file • puzzle.out

  7. Initial Puzzle • puzzle.in • 4ⅹ4ⅹ4 matrix • Consist of 1st, 2nd, 3rd,and 4th planes(4ⅹ4 matrix) • Total 16 lines • Example • 5 6 7 8 • 21 22 23 24 • 13 $ 15 16 • 17 18 19 20 • … • 30 33 41 60

  8. Input Command • Command Line • Input • sliding command • 1~6 • Input sequence file name • $>in [filename] • Output sequence file name • $>out [filename] • Example • $>1 • $>6 • $>in seq.in • $>out seq.out • $>3

  9. Sliding-Sequence File • In File • Contain lines of cell sliding-sequence • Each line contains maximum 10 operations • Example • 1364524351 • 2625342516 • 53…

  10. Output Puzzle • Command Line • Current puzzle status • Consist of 1st, 2nd, 3rd,and 4th planes(4ⅹ4 matrix) • Example • 5 6 7 8 | 25 26 27 28 | 33 40 41 43 | 44 45 46 47 • 21 22 23 24 | 1 2 3 4 | 34 39 42 48 | 53 54 55 56 • 9 10 11 12 | 29 30 31 32 | 35 38 49 50 | 57 58 59 60 • 13 $ 15 16 | 17 18 19 20 | 36 37 51 52 | 61 62 63 14

  11. Spec. • Assignment Spec. • System • Unix (junebug.snu.ac.kr) • Language • C/C++ • Compile • Use Makefile • $>make • Execution • $>./puzzle puzzle.in
