My code:
def bigger_together(array):
def convert(ar):
length = len(str(max(ar)))
return [(elem, length - len(elem)) for elem in map(str, ar)]
def get_number(ar, r):
return int(''.join(next(zip(*sorted(convert(ar), key=lambda x: x[0].ljust(x[1], '0'), reverse=r)))))
return get_number(array, True) - get_number(array, False)
This works correctly on a few examples, and on the rest incorrectly. I can not understand what key I need to use for sorting numbers. I think need to combine the length and number value. But I donâ€™t guess how.
On example:
for Extra 2 test I get two numbers: 3232212 and 1222332. But I need get 3322212 and 1222323.
