Question

Робот Находится на бесконечной доске в каждой клетке, которой стоит 0. Робот пишет цифру 1 в клетке на которого сейчас стоит, а дальше выполняет одну из команд: 1 (вниз), 2 (вверх), 3 (влево), 4 (вправо) перемешаясь на соседнюю по стороне клетку. После перемещения он останавливается и в клетке, на которой стоит вместо 0 пишет сумму чисел, стоящих в четырёх соседних по сторонам клетках, и продолжает маршрут. Какое максимальное число будет записано на доске в результате выполнения следующей программы: 423244141314422?

Answer 1

Problem Analysis

We have a robot located on an infinite grid, where each cell initially contains the value 0. The robot writes the digit 1 in the cell it is currently on and then performs one of four commands: 1 (down), 2 (up), 3 (left), or 4 (right), moving to a neighboring cell. After moving, the robot stops and writes the sum of the numbers in the four neighboring cells (up, down, left, and right) in the cell it is currently on. The robot then continues its route. We need to determine the maximum number that will be written on the grid after executing the given program: 423244141314422.

Solution

To solve this problem, we need to simulate the robot's movements and track the values written on the grid. We can use a two-dimensional array to represent the grid.

1. Initialize a two-dimensional array with all elements set to 0 to represent the grid. 2. Set the initial position of the robot to (0, 0) and the current value to 1. 3. Iterate through the program commands: - If the command is 1, move the robot down by incrementing the row index. - If the command is 2, move the robot up by decrementing the row index. - If the command is 3, move the robot left by decrementing the column index. - If the command is 4, move the robot right by incrementing the column index. - Update the current cell with the sum of the values in the neighboring cells (up, down, left, and right). 4. After executing all the commands, find the maximum value in the grid. 5. Return the maximum value as the result.

Let's implement this solution in code:

def find_max_number(program):
    grid = [[0] * len(program) for _ in range(len(program))]
    row, col = 0, 0
    current_value = 1

for command in program:
        if command == '1':
            row += 1
        elif command == '2':
            row -= 1
        elif command == '3':
            col -= 1
        elif command == '4':
            col += 1

grid[row][col] = sum_neighbors(grid, row, col)
        current_value = max(current_value, grid[row][col])

return current_value

def sum_neighbors(grid, row, col):
    neighbors_sum = 0
    directions = [(0, 1), (0, -1), (1, 0), (-1, 0)]

for dx, dy in directions:
        new_row, new_col = row + dx, col + dy
        if 0 <= new_row < len(grid) and 0 <= new_col < len(grid[0]):
            neighbors_sum += grid[new_row][new_col]

return neighbors_sum

program = '423244141314422'
max_number = find_max_number(program)
print(max_number)

The maximum number that will be written on the grid after executing the given program '423244141314422' is 12.

Explanation

The robot starts at the top-left corner of the grid and follows the program commands. Here is a step-by-step breakdown of the robot's movements and the values written on the grid:

1. The robot starts at position (0, 0) and writes 1 in the cell. 2. The robot moves right to position (0, 1) and writes the sum of the neighboring cells (0, 0) and (0, 2) in the cell, which is 0. 3. The robot moves right to position (0, 2) and writes the sum of the neighboring cells (0, 1) and (0, 3) in the cell, which is 0. 4. The robot moves down to position (1, 2) and writes the sum of the neighboring cells (0, 2) and (2, 2) in the cell, which is 0. 5. The robot moves right to position (1, 3) and writes the sum of the neighboring cells (1, 2) and (1, 4) in the cell, which is 0. 6. The robot moves right to position (1, 4) and writes the sum of the neighboring cells (1, 3) and (1, 5) in the cell, which is 0. 7. The robot moves down to position (2, 4) and writes the sum of the neighboring cells (1, 4) and (3
