function getIndexOfK(arr, k) {
  for (var i = 0; i < arr.length; i++) {
    var index = arr[i].indexOf(k);
    if (index > -1) {
      return [i, index];

  }
}

// Generate Sample Data
var k = 0;
var array = [];
for (var i = 0; i < 10; i++) {

    array[i].push(k);
  }
}
var needle = 130;
var result = getIndexOfK(array, needle);
