*Problem* Someone just won the Code Jam lottery, and we owe them *N* jamcoins! However, when we tried to print out an oversized check, we encountered a problem. The value of *N*, which is an integer, includes at least one digit that is a 4... and the 4 key on the keyboard of our oversized check printer is broken.
Fortunately, we have a workaround: we will send our winner two checks for positive integer amounts A and B, such that neither A nor B contains any digit that is a 4, and A + B = *N*. Please help us find any pair of values A and B that satisfy these conditions. *Input* The first line of the input gives the number of test cases, T. T test cases follow; each consists of one line with an integer N. *Output* For each test case, output one line containing Case #x: A B, where x is the test case number (starting from 1), and A and B are positive integers as described above. It is guaranteed that at least one solution exists. If there are multiple solutions, you may output any one of them. (See "What if a test case has multiple correct solutions?" in the Competing section of the FAQ. This information about multiple solutions will not be explicitly stated in the remainder of the 2019 contest.) *Here is the full problem:* https://codingcompetitions.withgoogle.com/codejam/round/0000000000051705/0000000000088231 *My solution:* *import redef missing_number(k, N): if not (1 < int(N) < 10**100) or '4' not in N: print() return pos = [i.start(0) for i in re.finditer('4', N)] inter_list = [i for i in N] for i in pos: inter_list[i] = '3' val = int(''.join(inter_list)) diff = int(N) - val print(f'Case #{k+1}:', diff, val)t = int(input())l = []for i in range(t): l.append(input())for t, N in enumerate(l): missing_number(t, N)* *Output*(on my system *)* *34 9404444Case #1: 1 3Case #2: 10 930Case #3: 1111 3333Two questions:* 1. Will Code Jam allow importing of modules like *re, numpy, pandas, itertools*? 2. If yes, why does my code end up in Runtime Error (RE) (I've tried with 60 digit number and works instantly in my system)? -- You received this message because you are subscribed to the Google Groups "Google Code Jam" group.
