##### isPrime?

import math
inp = int(input('Is this prime?\n> '))
isPrime=True

for i in range(2, int(math.sqrt(inp))+1):
    if inp % i == 0:
        isPrime=False
        break
    
print(f'{inp}  == prime is {isPrime}')

##### isBeautiful?

import math
num = int(input('Is this number beautiful?\n> '))

total = 1

for x in range(2, int(math.sqrt(num))+2):
    if not num % x:
        total *= x

if total == num:
    print(f'{num} is beautiful.')
    
else:
    print(f'{num} is ugly.')

##### isArm?

n,m = map(int,input('Input a range to check armstrong number?\n> ').split())
lis = []

for i in range(n, m+1):
    total = 0
    for x in str(i):
        total += int(x) ** len(str(i))
        
    if total == i:
        lis.append(int(i))

# 空集合(X
if not len(lis):
    print('There are no armstrong number between this range "(', end = '')

# print armstrong list in range
else:
    print('These number are armstrong number between this range\n> ', end = '')
    for i in lis:
        print(i, end = '')
        if i is not lis[-1]:
            print(', ', end = '')
            
print()

##### bubble-sort vs. bin-search

# global

val={}

# sort func_

def sort():
    for x in range(int(len(val))-1):
        for y in range(x+1,int(len(val))):
            # print(y)
            if val[x]>val[y]:
                tmp=val[x]
                val[x]=val[y]
                val[y]=tmp
    print(val)

#search func_

def search(g, l, r):
    mid=int((l+r)/2)
    
    if l>r:
        print('err0r')
        return
    
    elif val[mid] is g:
        print(f'index:{mid}')
        return
        
    elif val[mid]<g:
        search(g, mid+1, r)
        
    else:
        search(g, l, mid-1)

# main
n=int(input('input how many numbers in the array?\n> '))
print('input')
for i in range(n):
    val[i]=int(input(f'{i+1}. '))

sort()

m=int(input('input how many numbers need to search?\n> '))
print('input')

for i in range(m):
    tmp=int(input(f'{m}. '))
    search(tmp, 0, int(len(val))-1)

##### temperature-convert

temperature= input(('Input the temperature (included °C  or °F or K)\n> '))
temperature= temperature.split(' ')
temperature[1]= temperature[1].lower()
# print(temperature)

if temperature[1] == '°c':
    # print('C')
    temperature.insert(2, round(int(temperature[0])))

elif temperature[1] == '°k':
    # print('F')
    temperature.insert(2, round((int(temperature[0])-32)*5/9))

elif temperature[1] == 'k':
    # print('K')
    temperature.insert(2, round(int(temperature[0])-273.15))

else:
    print('3rr0r')

temperature.insert(3, round(temperature[2]*9/5+32))
temperature.insert(4, round(temperature[2]+273.15))

print(temperature)
