# Deletes all instances of given value in list. 
changes in that particular file
when we are deleting a node in that particular case we do not need to update the prev value otherwise prev will be pointed to the deleted node. So in the updated code, we will update prev only if the current node value is not equal to the target value. and the current node will be updated at every iteration
