i make a programe to find the number of divisor for a number with test case to submit it on the online judge so i write the code like that
num_case=int(raw_input())
num=list()
final_o=[]
for x in xrange(num_case):
num.append(int(raw_input()))
for h in num:
result=[int(h)]
for i in xrange(1, h + 1):
if h % i == 0:
result.append(i)
a=final_o.append(len(result)-1)
for ff in final_o:
print ff
in this case i make user input the number of test case for example 3 and then enter the number for example 12 7 and 36 then he get the output like this 6 2 9 that the 12 have 6 divisor number and so on this code work well but i get Memory Error when i submit it so i try to use itertools because range in for loop is small and xrange take a lot of time more than 2 second but i dont get any output code
from itertools import count
num_case=int(raw_input())
num=list()
final_o=[]
for x in xrange(num_case):
num.append(int(raw_input()))
for h in num:
result=[int(h)]
n=int(raw_input())
for i in count(1):
if n % i == 0:
result.append(i)
elif count==n+1:
break
a=final_o.append(len(result)-1)
for ff in final_o:
print ff
any one have a solution to this bug ? Note that the time for the test case 2 second and the range of the numbers is 10^9 and test case 100 How i Do that ?
def devisors_number(n):
result = 0
sqrt_n = int(n**0.5)
for i in xrange(1, sqrt_n + 1):
if n % i == 0:
result += 1
result *= 2
if sqrt_n**2 == n:
result -= 1
return result
n = int(raw_input("Enter a number: "))
d = devisors_number(n)
print "{0} has {1} devisors".format(n, d)
