请使用规范语句查询：
```java
// 注意是 inE().count().is(0)，而非 inE().is(0)
g.V(3).repeat(inE('child').outV().simplePath())
.until(or(inE().count().is(0),loops().is(eq(2))))
.path()
```
整理了一下示例数据：
```java
schema=graph.schema();
schema.vertexLabel('node').useCustomizeNumberId().create();
schema.edgeLabel('child').sourceLabel('node').targetLabel('node').create();
g.addV('node').property(id, 1).as('1')
.addV('node').property(id, 2).as('2')
.addV('node').property(id, 3).as('3')
.addV('node').property(id, 4).as('4')
.addE('child').from('1').to('2')
.addE('child').from('2').to('3')
.addE('child').from('4').to('3')
```
