Hi,

I am working on below challenge

http://codingbat.com/prob/p123837
I wrote my code as below
public int scoresAverage(int[] scores) {
  int result=0;
  int len=scores.length;
  int lenHalf=len/2;
  int sumEven=0;
    int sumOdd=0;
for(int i=0;i<lenHalf;i++){
    sumEven=(scores[i]+scores[i+1])/2;
    //result=sumeEven;
    //return result;
  }
  
  for(int i=lenHalf;i<len;i++){
    sumOdd=(scores[i]+scores[i+1])/2;
   // result=sumeOdd;
    //return result;
  }
  if(sumOdd>sumEven){
    return sumOdd;
  }
  else{
    return sumEven;
  }


}
return result;
  

}

}

Where is your pseudo code??
public int scoresAverage(int[] scores) {
  int result=0;
  int len=scores.length;
  int lenHalf=len/2;
  int sumEven=0;
    int sumOdd=0;
for(int i=0;i<lenHalf;i++){
    sumEven=(scores[i]+scores[i+1])/2;
    //result=sumeEven;
    //return result;
  }
  
  for(int i=lenHalf;i<len;i++){
    sumOdd=(scores[i]+scores[i+1])/2;
   // result=sumeOdd;
    //return result;
  }
  if(sumOdd>sumEven){
    return sumOdd;
  }
  else{
    return sumEven;
  }

    return result;

}

above passes all tests.
Any improvement, refinement, refactoring the code?

Psuedo Code:
1. loop through array
2. for arrays more than 2 elements find the average of left part and right part and return whichever greater
3. for array of 3 elements return the max out f both elements.
Keep only one return statement at end. it is bad practice to keep multiple return path from a function. Assign the result as per the requirement and finally return.
>>3. for array of 3 elements return the max out f both >>elements.

test case input 10, 20, 10
is the op that you r getting correct? what is expected?
