这次腾讯笔试做完后心(ti)情(jian)好(dan),所以po一下我的代码,供各位大佬diss一下
第一题 100
def test_1():
n = int(input())
array1 = input().split(" ")
m = int(input())
array2 = input().split(" ")
array1 = [int(num) for num in array1]
array2 = [int(num) for num in array2]
index1 = 0
index2 = 0
ans = []
while index1
if array1[index1] == array2[index2]:
ans.append(str(array1[index1]))
index1 += 1
index2 += 1
elif array1[index1] > array2[index2]:
index1 += 1
else:
index2 += 1
print(" ".join(ans))
第二题 100
这道题有点坑,题目说了 0~n-1的范围,但是我测试,包含n,这个太坑了,坑了我40多分钟查bug,对应代码就是5行和15行,多个+1就过了
def test_2():
tmp = input().split(" ")
n = int(tmp[0])
m = int(tmp[1])
team_dict = [[] for _ in range(n + 1)]
teams = []
for i in range(m):
tmp = input().split(" ")[1:]
tmp = [int(num) for num in tmp]
teams.append(tmp)
for p_num in tmp:
team_dict[p_num].append(i)
stack = [0]
visited = [False] * m
informed = [False] * (n + 1)
informed[0] = True
index = 0
while index
tmp_p = stack[index]
tmp_team = team_dict[tmp_p]
for team_num in tmp_team:
if visited[team_num]:
continue
for person in teams[team_num]:
if informed[person]:
continue
stack.append(person)
informed[person] = True
visited[team_num] = True
index += 1
print(informed.count(True)) 第三题 100
def test_3():
tmp = input().split(" ")
n = int(tmp[0])
k = int(tmp[1])
str_dict = {}
for _ in range(n):
tmp = input()
str_dict[tmp] = str_dict.get(tmp, 0) + 1
tmp_list = []
for key in str_dict.keys():
tmp_list.append((key, str_dict[key]))
list2 = sorted(tmp_list, key=lambda x: [x[1], x[0]])
list1 = sorted(tmp_list, key=lambda x: [-x[1], x[0]])
for i in range(k):
print(list1[i][0], list1[i][1])
for i in range(k):
print(list2[i][0], list2[i][1])
第四题 100
def test_4():
n = int(input())
nums = input().split(" ")
index_nums = []
for i in range(len(nums)):
index_nums.append((i, int(nums[i])))
order_nums = sorted(index_nums, key=lambda x: [x[1], x[0]])
indexs = [0] * n
for i in range(len(order_nums)):
indexs[order_nums[i][0]] = i
for i in indexs:
if i > n / 2 - 1:
print(order_nums[n // 2 - 1][1])
else:
print(order_nums[n // 2][1])
return
