1.已知乙個數字列表，求列表中心元素。
num = [78, 67, 52, 78, 99, 23]
n = len(num)
if n % 2 == 0:
x = n // 2
y = n // 2 -1
print(num[x], num[y])
else:
print(num[n//2])
num = [78, 67, 52, 78, 99, 23]
total_num = 0
for s in num:
total_num += s
print(total_num)
num = [78, 67, 52, 78, 99, 23]
total_num = 0
n = 0
for s in num:
n += 1
if n & 1 == 1:
total_num = s
print(total_num, end = " ")
sum = [59, 54, 89, 45, 78, 45, 12, 96, 789, 45, 69]
for i in range(0, len(sum)):
if sum[i] % 2 == 1:
print(sum[i])
例如：nums = [1, 2, 3, 4] —> nums = [2, 4, 6, 8]
nums = [1, 2, 3, 4]
x = 0
for n in nums:
nums[x] = n * 2
x += 1
print(nums)
例如:names = [『張三』, 『李四』, 『大黃』, 『張三』] -> names = [『張三』, 『李四』, 『大黃』]
names = ['張三', '李四', '大黃', '張三']
names1 = names * 1
names2 =
for n in names:
for m in names1:
if n == m and n not in names2:
names = names2
print(names)
scores = [9, 6, 7, 8, 5, 9, 9, 4, 6]
max = min = scores[0]
n = 0
for m in range(len(scores)):
if max < scores[m]:
max = scores[m]
elif min > scores[m]:
min = scores[m]
n += scores[m]
print('最後總分：', (n - max - min) / (len(scores)))
例如: a = [1, 『a』, 4, 90] b = [『a』, 8, 『j』, 1] --> c = [1, 『a』]
a = [1, 'a', 4, 90]
b = ['a', 8, 'j', 1]
c =
for i in range(len(a)):
for j in range(len(b)):
if a[i] == b[j] and n not in c:
print(c)
例如: nums = [19, 89, 90, 600, 1] —> 600
nums = [19, 89, 90, 600, 1]
max = 0
for i in range(len(nums)):
if max < nums[i]:
max = nums[i]
print(max)
例如：nums = [1, 2, 3,1,4,2,1,3,7,3,3] —> 列印:3
nums = [1, 2, 3, 1, 4, 2, 1, 3, 7, 3, 3]
n = 0
m = 0
x = 0
for i in nums:
n = nums.count(i)
if n > m:
m = n
x = i
print(i)

湖南集訓Day4
上午的數論感覺還可以，嗯，感覺。因為畢竟我數學弱，只聽懂一半什麼的，感覺證明還是比較顯然的。話說這金牌爺長得好像我某物理老師啊 下午的題終於不是clj出的了，沒辣麼虐了。第一題疑似回文自動機，然而並不會，於是dp水了60分。第二題想了下應該是樹鏈剖分，然後發現搞不出來，回去水第一題，然後水完回來繼續...
