Delete all nodes in a linked list

Linked list each node are create dynamically in heap area. And each node can we contains many number of instance variables (for data fields and pointer fields). Therefore that is very important remove all linked list node when linked list are no longer need. Because that is are best way to utilize heap area memory and avoid memory overflow problem.

Suppose we are inserted the following (1,2,3,4,5,6) node in a sequence.

Here given code implementation process.

1) Remove linked list nodes one by one in c 2) Remove linked list nodes one by one in c++ 3) Remove linked list nodes one by one in java 4) Remove linked list nodes one by one in c# 5) Remove linked list nodes one by one in golang 6) Remove linked list nodes one by one in php 7) Remove linked list nodes one by one in node js 8) Remove linked list nodes one by one in typescript 9) Remove linked list nodes one by one in python 10) Remove linked list nodes one by one in ruby 11) Remove linked list nodes one by one in scala 12) Remove linked list nodes one by one in swift 13) Remove linked list nodes one by one in kotlin 14) Remove linked list nodes one by one in vb.net
