Delete elements from an array given an array of indices

A rough "it works" way to delete elements from an array given the array of indices to delete. A new array is created by copying over the remaining elements.

Any suggestions on how to make this more efficient appreciated :)

  12.                 chkIndex++;
  13.             } else {
  14.                 newData[copyIndex++] = data[i];
