# --description--
|
|
|
|
Given an array of clue numbers and an array of cells, determine whether the cells satisfy the nonogram clue.
|
|
|
|
- The clue is an array of numbers representing the lengths of consecutive filled cells, in order. For example, a clue of `[3, 2]` means there should be 3 consecutive filled cells followed by 2 consecutive filled cells, separated by at least one empty cell.
|
|
- The row is an array of 1s (filled) and 0s (empty).
|
|
