Hi,

i am  trying below challenge

http://codingbat.com/prob/p110019

I have not understood on problem statement when they say like
count instances where the second "6" is actually a 7.

i wrote as below

public int array667(int[] nums) {
int count=0;
  for(int i=0;i<nums.length-1;i++)
  {
  if(nums[i]==nums[i+1])
  count++;
  }
  return count;
}

some test cases are failing as below
Expected      Run            
array667({6, 6, 2}) → 1      1      OK         
array667({6, 6, 2, 6}) → 1      1      OK         
array667({6, 7, 2, 6}) → 1      0      X         
array667({6, 6, 2, 6, 7}) → 2      1      X         
array667({1, 6, 3}) → 0      0      OK         
array667({6, 1}) → 0      0      OK         
array667({}) → 0      0      OK         
array667({3, 6, 7, 6}) → 1      0      X         
array667({3, 6, 6, 7}) → 2      1      X         
array667({6, 3, 6, 6}) → 1      1      OK         
array667({6, 7, 6, 6}) → 2      1      X         
array667({1, 2, 3, 5, 6}) → 0      0      OK         
array667({1, 2, 3, 6, 6}) → 1      1      OK
