/** 编写一个 js 方法根据输入实现输出 将 arr 转化为树形结构 treeObj 节点的 outputs 为下一节点的 inputs */

例子： // 输入 const arr = [{ name: ‘test1’, outputs: [1,2], inputs: [] }, { name: ‘test2’, outputs: [3], inputs: [1] }, { name: ‘test3’, outputs: [4], inputs: [2] }, { name: ‘test4’, outputs: [5], inputs: [3,4] }, { name: ‘test5’, outputs: [], inputs: [5] }] // 输出 const treeObj = { name: ‘test1’, outputs: [1,2], inputs: [] children: [{ name: ‘test2’, outputs: [3], inputs: [1], children: [{ name: ‘test4’, outputs: [5], inputs: [3,4], children: [{ name: ‘test5’, outputs: [], inputs: [5], children: null }] }] }, { name: ‘test3’, outputs: [4], inputs: [2], children: [{ name: ‘test4’, outputs: [5], inputs: [3,4], children: [{ name: ‘test5’, outputs: [], inputs: [5], children: null }] }] }] }
