猿辅导笔试题
第一题，螺旋矩阵100%
while True:
try:
line = list(map(int, input().strip().split()))
n, m = line[0], line[1]
matrix = []
for i in range(n):
line = list(map(int, input().strip().split()))
matrix.append(line)
i, j, di, dj = 0, 0, 1, 0
res = []
for _ in range(n * m):
res.append(matrix[i][j])
matrix[i][j] = -1
if matrix[(i + di) % n][(j + dj) % m] == -1:
di, dj = -dj, di
i += di
j += dj
print(' '.join([str(x) for x in res]))
except:
break
第二题，滑动窗口法，100%（注意判断条件不然会是0%） while True: try: line = list(map(int, input().strip().split())) n, s = line[0], line[1] nums = list(map(int, input().strip().split())) l, r = 0, 0 max_len = 0 cur_sum = 0 while r < n: cur_sum += nums[r] r += 1 while cur_sum > s: max_len = max(max_len, r - l - 1) cur_sum -= nums[l] l += 1 print(max_len) except: break第三题，一看就烦，不写了告辞，0%
