Because He begin walk from 0 to 2 and from 2 to -2 so calculate it and you'll take 6 not 4;

-10 ... -4 .. -2 -1 0 1 2

m = 0;

from 0 to 1 m = 1;

from 1 to 2 m = 2;

from 2 to 1 m = 3;

from 1 to 0 m = 4;

from 0 to -1 m =5;

from -1 to -2(exit) m = 6;

n = 0;

from 0 to -1 n = 1;

from 0 to -2 n = 2;

answer 6 2

so did you understand?
