For problem statement at 1000-1999/1400-1499/1480-1489/1482/problemE.txt this is a correct solution, but verifier at 1000-1999/1400-1499/1480-1489/1482/verifierE.go ends with test 1 mismatch
expected: 0
got: 5

exit status 1 can you fix the verifier? ```go

	// Maintain a stack of (height, max_dp_val) where max_dp_val represents
	// the best dp[j-1] achievable when h[k] is the minimum of the segment.

	// of potential left endpoints where a certain building is the minimum.
