- Lists with numbers
- Increasing/Decreasing rows
- Find word int text. (Lexer or Regex)
- Grid. Find pattern in 2D
- Find correct rows in list 2, based on rules in list 2
- Grid. Path seeking. Used "parser-inspiration" and generics and embedded structs.
- Tricky. Recursion. Finding operators to match result.
- Easy. Grid.
- Parsing lines.
- Pathfinding. BFS.
- Tricky. Recursion. 2nd very deep. Memoization. lenInt() and divideInt()
- Grid w regions. BFS. Finding area + perimeter + sides
- Linear Equation System. Gauss elimination. Big mumbers.
- Easy. Robots moving speed+pos. Weird 2nd: looking for christmas tree
- Grid. BFS. BubbleTea for visualization.
- Hard. Grid. Pathfinding. BFS. Dijkstra + backtracking
- Simulate a machine. Reverse engineering program
