# What's wrong with my python code?

• In my code, i is the index move from low digit to higher. j is the index to digits lower than i.
At first, it finds the index maxID with smallest value but higher than i,
if find such maxID, then
swap the maxID and i th data in the given list, and
adjust the following digits to make it as small as possible
else
return the list with the smallest value

And I got the "Runtime Error Message: Line 58: TypeError: nextPermutation() takes exactly 1 argument (2 given) when Last executed input:[1]"

I can run my code in my computer. Please help me to check my code. Thanks a lot.

``````class Solution:
# @param num, a list of integer
# @return a list of integer
def nextPermutation(num):
for i in reversed(range(len(num))):
maxID = i
if i == len(num) - 1:
break
for j in reversed(range(i+1,len(num))):
if maxID==i and num[maxID] < num[j]:
maxID = j
if maxID !=i and num[maxID] > num[j] and num[i] < num[j]:
maxID = j
if maxID == i:
continue
else:
t = num[i]
num[i] = num[maxID]
num[maxID] = t
##minimize following
for v in range(i+1,len(num)):
minID = v
if v == len(num)-1:
break
for u in range(v+1,len(num)):
if num[minID] > num[u]:
minID = u
if minID == v:
continue
else:
t = num[v]
num[v] = num[minID]
num[minID] = t
return num
for i in range(len(num)):
minID = i
if i == len(num) - 1:
break
for j in range(i+1,len(num)):
if num[minID] > num[j]:
minID = j
if minID == i:
continue
else:
t = num[i]
num[i] = num[j]
num[j] = t
return num``````

• you must have modified "def permutation(num)" which should be "def permutation(self, num)"
