从嵌套数组和父数组中删除重复项

function removeDuplicates(nestedArray, parentArray) {
  const seen = new Set();
  
  for (let i = 0; i < parentArray.length; i++) {
    const currentArray = nestedArray[i];
    const newArray = [];
    
    for (let j = 0; j < currentArray.length; j++) {
      const currentElement = currentArray[j];
      
      if (!seen.has(currentElement)) {
        seen.add(currentElement);
        newArray.push(currentElement);
      }
    }
    
    nestedArray[i] = newArray;
  }
  
  return nestedArray;
}

// 示例用法
const nestedArray = [[1, 2, 3], [2, 3, 4], [3, 4, 5]];
const parentArray = [nestedArray[0], nestedArray[1], nestedArray[2]];

const result = removeDuplicates(nestedArray, parentArray);
console.log(result);
