好的,下面是完整的代码:
```python
d = []
with open('cellpicture.txt') as f:
m,n = map(int,f.readline().split())
for x in range(m):
r = list(map(int,f.readline()[:n]))
d.append(r)
for x in d:
print(x)
def explorePixel(d,m,n,i,j):
q = [(i,j)]
while q:
x,y = q.pop(0)
if d[x][y] < 0:
continue
d[x][y] = 0 - d[x][y]
if x > 0 and d[x-1][y] > 0:
q.append((x-1,y))
if x < (m-1) and d[x+1][y] > 0:
q.append((x+1,y))
if y > 0 and d[x][y-1] > 0:
q.append((x,y-1))
if y < (n-1) and d[x][y+1] > 0:
q.append((x,y+1))
iCellCount = 0
for i in range(m):
for j in range(n):
if d[i][j] > 0:
explorePixel(d,m,n,i,j)
iCellCount += 1
print(iCellCount)
```
这段代码主要是读取一个文本文件`cellpicture.txt`中的数据,然后根据数据中的数字构建一个二维的矩阵,表示一个细胞图。接着,代码定义了一个函数`explorePixel`用于宽度优先遍历图中的像素点,并标记已经访问过的像素点。最后,代码遍历整个细胞图,找到还没有被访问过的像素点,并使用`explorePixel`函数对其进行遍历,计算细胞的数量并输出结果。
