Keyscape Challenge Code

Keyscape refers to any polyphonic keyboard interface capable of detecting:

KeyScape Challenge Code aims to:

For the purpose of this example, let's assume we have a basic implementation of the KeyScape challenge in Python: keyscape challenge code

from collections import deque
def keyscape(grid):
    # Find start and end keys
    start = None
    end = None
    for i in range(len(grid)):
        for j in range(len(grid[0])):
            if grid[i][j] == 'S':
                start = (i, j)
            elif grid[i][j] == 'E':
                end = (i, j)
# Perform BFS to find shortest path
    queue = deque([(start, [start])])
    visited = set([start])
while queue:
        (x, y), path = queue.popleft()
        if (x, y) == end:
            return path
for dx, dy in [(0, 1), (0, -1), (1, 0), (-1, 0)]:
            nx, ny = x + dx, y + dy
            if (0 <= nx < len(grid) and 0 <= ny < len(grid[0]) and
                    grid[nx][ny] != '#' and (nx, ny) not in visited):
                queue.append(((nx, ny), path + [(nx, ny)]))
                visited.add((nx, ny))
return None
