删除包含某个指定元素的数组元素，并将它们放在最后

function removeAndMoveToEnd(arr, target) {
  let removedElements = [];
  let i = 0;
  
  while (i < arr.length) {
    if (arr[i] === target) {
      removedElements.push(arr.splice(i, 1)[0]);
    } else {
      i++;
    }
  }
  
  arr.push(...removedElements);
  
  return arr;
}

// 示例用法
const array = [1, 2, 3, 4, 5, 2, 6, 7, 2];
const targetElement = 2;

const result = removeAndMoveToEnd(array, targetElement);
console.log(result); // 输出 [1, 3, 4, 5, 6, 7, 2, 2, 2]
