print("Hello World!")

L1-002 打印沙漏

import math

n, c = input().split() n = int(n) h = int(math.sqrt((n + 1) // 2))

# 打印上半层沙漏 for i in range(h): print(" " i + c (2 * (h - i) - 1))

# 打印下半层沙漏 for i in range(2, h + 1): print(" " (h - i) + c (2 * i - 1))

remaining_symbols = n - 2 h h + 1 print(remaining_symbols)

L1-003 个位数统计

s = input() a = [0] * 10

for char in s: digit = int(char) a[digit] += 1

for i in range(10): if a[i] != 0: print(f"{i}:{a[i]}")

L1-004 计算摄氏温度

f = int(input()) celsius = 5 * (f - 32) / 9 print("Celsius =", int(celsius))

L1-005 考试座位号

N=int(input()) a=[] b=[] c=[] for i in range(N): t=input().split() a.append(t[0]) b.append(int(t[1])) #因为我们要查询它在列表中位置，所以得用int() c.append(t[2]) t=int(input()) d=input().split() for i in d: t=b.index(int(i)) #通过index()方法找到位置 print(a[t],c[t])

L1-006 连续因子

import math

n = int(input()) m = 0 mm = -1 for i in range(2, int(math.sqrt(n))+1): if n % i == 0: j = i + 1 t = n / i while t % j == 0: t = t / j j = j + 1 if j - i > m: m = j - i mm = i

if mm != -1: # 可能有质数的情况 print(m) s = str(mm) for i in range(mm + 1, mm + m): s = s + "*" + str(i) print(s) else: print(1) print(n)

L1-007 念数字

dict={'-':'fu','0':'ling','1':'yi','2':'er','3':'san','4':'si','5':'wu', '6':'liu','7':'qi','8':'ba','9':'jiu'} a=input() for i in range(len(a)-1): print(dict[a[i]],end=" ") print(dict[a[len(a)-1]])

L1-008 求整数段和

a=input().split() sum=0 cnt=0 for i in range(int(a[0]),int(a[1])+1): sum=int(i)+sum if cnt%5==0 and cnt!=0 : print() print("%5d"%i,end="") cnt=cnt+1 print("\nSum = %d"%sum)

L1-009 N个数求和

# 又是为大数舒服的一题 def gcd(a, b): while b != 0: c = a % b a = b b = c return a

n = int(input()) s = input().split()

mu = 1 for i in s: i = i.split("/") mu = mu int(i[1]) zi = 0 for i in s: i = i.split("/") zi = zi + int(i[0]) mu // int(i[1])

t = gcd(abs(zi), mu) zi = zi // t mu = mu // t

if zi == 0: # 为零的情况,测试点6 print(0)

flag = False if abs(zi) >= mu: # 分子为负数的情况，测试点4.5 print(zi//mu, end="") flag = True

if abs(zi)%mu != 0: if flag: print(end=" ") if zi < 0: print(end="-") zi = abs(zi) print(zi%mu, mu,sep="/")

L1-010 比较大小

a=input().split() b=[] for i in a: b.append(int(i)) b.sort() for i in b[0:len(b)-1]: print(i,end="->") print(b[len(b)-1])
