问尝试创建一个平衡值的泛型函数(不确定如何准确地表达它)

EN

// for every item in the bucket
for(var i = 0; i < buckets.length; i++){

  // if the value of this bucket is negative
  if(buckets[i].value < 0) {

    // look through every bucket again
    for(var j = 0; j < buckets.length; j++) {

      // and if we find one that is positive
      if(buckets[j].value > 0) {

        // add all the positive to this negative
        buckets[i].value += buckets[j].value;

        // if it's still negative we are gonna start again
        if(buckets[i].value < 0) {

          i--;
          break;
        }
