Complete the function squareRoot that will result in the following solution of isSquareRoot to pass the tests provided. Of course, you shouldn't use Math.sqrt(). Due to the nature of codingbat, you need to copy the partially-completed template below into the answer box first.

boolean isSquareRoot(double a, double b) {
   double root = squareRoot(a);
   if(Math.abs(a - b*b) <= a/100.0) {
      return true;
   }
   return false;
}

double squareRoot(int val) {
   //to be completed
}
