# Begin.

Sometimes you write a code, this code simple actually and not hard to think about it. When you finish the code, you realize something. That code amazing. First of all code is working okay :) and you feel it's like a magic. Maybe it could be better, but for now this is the best.

|
```python
|
|
#!/usr/bin/python3
|
|
|
|
# Given array has some integers.
|
|
|
|
# We are trying to find max difference between an integer in array and situated in array more lower index integers.
|
|
|
|
# If difference under 0 result should be -1.
|
|
|
|
def maxDifference(a):
|
|
max_difference = -1
|
|
|
|
for i1 in range(len(a)):
|
|
|
|
for i2 in range(i1):
|
|
|
|
difference = a[i1] - a[i2]
|
|
|
|
if difference > 0 and difference > max_difference:
|
|
max_difference = difference
|
|
|
|
return max_difference
|
|
|
|
if __name__ == '__main__':
|
|
|
|
a = [6, 5, 10, 2, 1, 9, 3]
|
|
print(maxDifference(a)) # => Result 8 because for this example, max difference between 9 - 1 = 8.
|
|
```
