DR288 pairs 0-Based vs 1-Based Indexing (Engine array col[k] (0-based) vs learner label Column k+1 (1-based)) with Question-Driven Modality (Self-Test Triage): learners verify Array index col[0] corresponds to Display Column 1 on the RoadLegend, master Coordinate Index Translation Between Engine and Display Grid, and eliminate off-by-one lookup errors when translating array index k to display columns.
DR288 drill board (PPBBPPPPBBPBBBPBPPBBPBTBP): 13 Big Road columns, 21 Big Eye Boy, 19 Small Road, and 15 Cockroach Pig marks.
This bead is at Row 3. Column 2 stopped at Row 2, one row above → blue (≠).
Common table reading watchout: Thinking "no bead at this row" means blue. It is blue only when Column 2 stopped exactly one row above this bead.
Column 3 has 4 beads. Column 1 has 2 beads. Different depth → blue (≠).
Common table reading watchout: Comparing the wrong columns. Compare Column 3, the one that just finished, with Column 1.
Column 4 has 2 beads. Column 1 has 2 beads. Same depth → red (=).
Common table reading watchout: Comparing the wrong columns. Compare Column 4, the one that just finished, with Column 1.
Engine array col[k] (0-based) vs learner label Column k+1 (1-based)
Coordinate Index Translation Between Engine and Display Grid
Array index col[0] corresponds to Display Column 1 on the RoadLegend
Off-by-one lookup errors when translating array index k to display columns
Convert cleanly between 1-based display labels and 0-based engine indices by diagnosing off-by-one column lookbacks and Case 2b vs Case 2c mixups
In DR288, Question-Driven Error Audit transforms 0-Based vs 1-Based Indexing into a repeatable check of Array index col[0] corresponds to Display Column 1 on the RoadLegend, eliminating off-by-one lookup errors when translating array index k to display columns on sequence PPBBPPPPB.
Matrix comparison DR288 under Question-Driven Error Audit reads: This bead is at Row 3. Column 2 stopped at Row 2, one row above → blue (≠). With 19 Small Road and 15 Cockroach Pig marks plotted, Array index col[0] corresponds to Display Column 1 on the RoadLegend is verified.
| DR288 Drill Dimension | Coordinate / Rule | GMU Modality Action |
|---|---|---|
| DR288 Matrix Coordinate | Engine array col[k] (0-based) vs learner label Column k+1 (1-based) | Question-Driven Modality (Self-Test Triage) |
| DR288 Rule & Depth | Coordinate Index Translation Between Engine and Display Grid | Array index col[0] corresponds to Display Column 1 on the RoadLegend |
| DR288 Diagnostic Target | Off-by-one lookup errors when translating array index k to display columns | Convert cleanly between 1-based display labels and 0-based engine indices |
As DR288 concludes for 0-Based vs 1-Based Indexing, Column 3 has 4 beads. Column 1 has 2 beads. Different depth → blue (≠). Practicing diagnosing off-by-one column lookbacks and Case 2b vs Case 2c mixups across 13 streaks answers Where does an off-by-one column count flip the derived mark color?
