Program Breaks for certain cases

[rahul-anb]

I was looking into this code, it works for almost all but breaks for certain set of numbers

mt: 7 8 9 10 11 12 13 14 23 24 25 26 41 42 43
dc: 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63

Ive put the example for which the program breaks and gives the following error

The same is happening with me. Any suggestions? @fernando170 @int-main

There seems to be a bug in the implementation of Petrick's method, which is executed when len(chart) != 0.
I have submitted a pull request to fix this.
