solution係乜？無讀dse
recursion已經唔係clean code
明明一直以來都唔駛用break statement
This post doesn’t look nice
do.. while head != null
眼殘自膠
試吓
do{
head=head.next;
System.out.println(head)
}while(head.next!=null)
試吓
do{
head=head.next;
System.out.println(head)
}while(head.next!=null)
會miss咗第1粒
你由head出發點會miss到第一粒
如果你問題問嘅係「由node a iterate 到node d唔iterate出界」而唔係由head開始，咁你每個node要做iterate 同 print 2樣嘢，totally要3次iterate同4次print。你個loop寫到識跳舞都冇用，你都係兩種：
1.個loop包少咗次print，你喺loop出面死死氣寫多個print
2.個loop包多咗次iterate，你喺loop入面死死氣俾個if
