pre-process so that I known if there is a1 < nums[i] and a2 > nums[i], and if there are, should return True, else return False

```
class Solution(object):
def increasingTriplet(self, nums):
if len(nums) < 3:
return False
less, more = [ 0 for i in xrange(len(nums)) ], [ 0 for i in xrange(len(nums)) ]
mini = nums[0]
for i in xrange(1, len(nums)):
if nums[i] > mini:
less[i] = 1
else:
mini = nums[i]
maxim = nums[-1]
for i in xrange(len(nums) - 2, -1, -1):
if nums[i] < maxim:
more[i] = 1
else:
maxim = nums[i]
for i in xrange(len(nums)):
if less[i] and more[i]:
return True
return False
```
