1.Equal Neighbors

Write a function that finds the number of equal neighbor pairs inside a matrix of variable size and type (numbers or strings).

The input comes as array of arrays, containing string elements (2D matrix of strings).

The output is return value of you function. Save the number of equal pairs you find and return it.

Best Answer

Actually he is missing the case when the current element of the matrix have 2 neighbors at the same time- the next element of the row and element from the next row.

In this case you have to add 2 units to the counter. To fix that you just have to split the check on line 9 in 2 separate checks:

if(col === row[j+1]){
counter++;
}
if(col === arr[i+1][j]){
counter++;
}

Added to your solution looks like that: https://pastebin.com/e7zZuR21

The second check in line else if (col === row[j + 1] || col === arr[i][j + 1]) is useless as row = arr[i] and you check the exact same thing twice(in case the first one is false), however it does not affect your score.
