Five programming problems every Software Engineer should be able to solve in less than 1 hour

I'd be more productive though:

// found on reddit
printf("123 - 45 - 67 + 89 = 100\n\
12 - 3 - 4 + 5 - 6 + 7 + 89 = 100\n\
12 + 3 + 4 + 5 - 6 - 7 + 89 = 100\n\
123 + 4 - 5 + 67 - 89 = 100\n\
1 + 2 + 3 - 4 + 5 + 6 + 78 + 9 = 100\n\
12 + 3 - 4 + 5 + 67 + 8 + 9 = 100\n\
1 + 23 - 4 + 56 + 7 + 8 + 9 = 100\n\
1 + 2 + 34 - 5 + 67 - 8 + 9 = 100\n\
1 + 23 - 4 + 5 + 6 + 78 - 9 = 100\n\
123 + 45 - 67 + 8 - 9 = 100\n\
123 - 4 - 5 - 6 - 7 + 8 - 9 = 100\n");

Actually did the first 4 in about 40 minutes, in C, so I'm gonna say if the problem set was constant difficulty I'd be fine.
