Remove duplicate element pairs from multidimensional array

Question

I have an array that looks like this:

1.  coordinates = [ [16.343345, 35.123523],
2.                  [14.325423, 34.632723],
3.                  [15.231512,         


        

Answer 1

I am not sure about coordinates[][] dataType. Make the comparison accordingly.

  var dubJRows= new Array();
  for(int i = 0; i <  coordinates.length -2; i++){
    for(int j = i+1; j <  coordinates.length -1; j++){
        if (i != j && chk_dubJRows_not_contains(j)) {
           innerArray1 [1][1] = coordinates[i];
           innerArray2 [1][1] = coordinates[j];
           if ( innerArray1 [1][0] == innerArray2[1][0] 
                   && innerArray1[1][1] == innerArray2[1][1]) {
               dubJRows.push(j);
            }
         }
       }
    }
    //REMOVE ALL dubJRows from coordinates.
