The code i have in Java should perform the following task:

My code below is supposed to perform this task but when I run the test cases, most of them fail. Can you please tell me what my error is?

CODE

public static int longestSeq (int[] array) {

if (array.length == 0) {

return 0;

}

int maxSeq = 0;

int counter = 0;

for (int i = 0; i

if (array[i] == array[i-1] + 1) {

counter++;

if (counter > maxSeq) {

maxSeq = counter;

}

else {

// reset counter

counter = 0;

}}}

return maxSeq; }

TEST CASES

Write a method named longestSeq that takes as a parameter an array if integers. The method should return the length of the longest consecutive sequence of integers in the array. For example, if the array has the following values: [7,9,10,3,2,1,12,20], there are 2 consecutive sequences (9,10),(3,2,1). The longest one is the second sequence; hence the method should return 3. If there are no consecutive sequences in the array, the method should return 1 . If the array is empty the return value is 0
