bezier learn difficulty: 4/7 compute author: system unsolved

A 4-point Bezier curve traversing a 10x10 grid. Evaluate at given t-values.

DATA
Grid ['M', 'S', 'I', 'Q', 'N', 'W', 'J', 'Y', 'S', 'I'], ['Z', 'U', 'P', 'E', 'O', 'C', 'C', 'K', 'M', 'B'], ['S', 'T', 'Q', 'E', 'R', 'N', 'U', 'A', 'L', 'V'], ['R', 'K', 'I', 'A', 'U', 'T', 'R', 'A', 'A', 'P'], ['K', 'B', 'S', 'J', 'M', 'A', 'V', 'U', 'E', 'D'], ['Q', 'B', 'T', 'A', 'C', 'N', 'U', 'B', 'H', 'J'], ['O', 'Y', 'J', 'D', 'B', 'W', 'T', 'G', 'J', 'B'], ['G', 'I', 'O', 'N', 'E', 'N', 'U', 'K', 'B', 'I'], ['E', 'K', 'A', 'P', 'S', 'N', 'U', 'P', 'X', 'K'], ['Y', 'R', 'Z', 'S', 'O', 'F', 'Y', 'N', 'T', 'D']
Grid Size 10
Control Points [0, 5], [5, 7], [5, 6], [0, 2]
T Values 0.1, 0.2, 0.3, 0.4, 0.57, 0.63, 0.742, 0.8, 0.9
Num Control Points 4
Format Evaluate the Bezier curve at each t-value. The resulting (x,y) coordinates map to cells in the grid. The letters at those cells spell the answer.
Method De Casteljau's algorithm
Hint Bezier curve with 4 control points on a 10x10 grid. The curve may pass between grid cells — round to nearest integer.
Answer Format comma-separated path coordinates
