原始數據：
{
name: '1',
children: [
{ name: '2', children: [{ name: '5' }] },
{ name: '3', children: [{ name: '6' }] },
{ name: '4', children: [{ name: '7' }] },
]
}
期望結果數據：
{
"name": "1第一層級",
"children": [{
"name": "2第二層級",
"children": [{
"name": "5第三層級"
}]
}, {
"name": "3第二層級",
"children": [{
"name": "6第三層級"
}]
}, {
"name": "4第二層級",
"children": [{
"name": "7第三層級"
}]
}]
}
