For problem statement at 1000-1999/1300-1399/1320-1329/1322/problemD.txt this is a correct solution, but verifier at 1000-1999/1300-1399/1320-1329/1322/verifierD.go ends with case 27 failed: expected 3 got 6
input:
5 3
3 2 3 2 2
4 5 0 4 0
5 1 5 -4 4 1 2 -4


exit status 1 can you fix the verifier? package main
