去除子数组，使数组左右和相等

function findEqualSumSubarray(arr) {
  const sum = arr.reduce((acc, cur) => acc + cur, 0);
  let leftSum = 0;
  const tempArray = [];

  for (let i = 0; i < arr.length; i++) {
    if (leftSum === sum - arr[i]) {
      return tempArray;
    }
    leftSum += arr[i];
    tempArray.push(arr[i]);
  }

  return [];
}

// 示例用法
const array = [1, 2, 3, 4, 5, 5];
const result = findEqualSumSubarray(array);
console.log(result); // 输出 [1, 2, 3, 4, 5]
