The program I wrote by using 'for loop' is correct and passed all the testcases,however, when I transfer 'for loop' to 'while loop',an 'IndexError' occurred,I wonder what are the problems in my program which using 'while loop'.
nums = []
remainders=[]
while True:
num=int(input('Number: '))
if num==0:
break
nums.append(num)
if len(nums)==0:
print('No integers were entered')
exit()
a=0
while a<len(nums):
num=nums[a]
remainder=num%10
remainders.append(remainder)
a+=1
index=remainders.index(max(remainders))
count=0
for i in remainders:
if i > remainder:
remainder=i
count=0
if i ==remainder:
count+=1
if count ==1:
print('The most interesting integer was: {}'.format(nums[index]))
elif count>1 and count<len(nums):
print('Two or more integers are the most interesting')
else:
print('All integers have the same remainder')
That's the program I wrote by using for loop, this answer is correct
nums = []
remainders=[]
while True:
num=int(input('Number: '))
if num==0:
break
nums.append(num)
if len(nums)==0:
print('No integers were entered')
exit()
a=0
while a<len(nums):
num=nums[a]
remainder=num%10
remainders.append(remainder)
a+=1
index=remainders.index(max(remainders))
count=0
k=0
while k<len(remainders):
remainder=remainders[k]
if remainders[k]>remainder:
remainder=remainders[k]
count=0
k+=1
if remainders[k]==remainder:
count+=1
k+=1
if count ==1:
print('The most interesting integer was: {}'.format(nums[index]))
elif count>1 and count<len(nums):
print('Two or more integers are the most interesting')
else:
print('All integers have the same remainder')
This answer is incorrect because the second while loop have some problems
actual:
Number: 4
Number: 20
Number: 9
Number: 3
Number: 5
Number: 0
Traceback (most recent call last):
File "numbers.py", line 26, in <module>
if remainders[k]==remainder:
IndexError: list index out of range
expected:
Number: 4
Number: 20
Number: 9
Number: 3
Number: 5
Number: 0
The most interesting integer was: 9
