1. One-dimensional array A has n pieces of data.
When obtaining the data of element index i in array A, what is the time complexity?
When the element data in array A is 7999, what is the time complexity?
2. Complexity analysis of one-way link series (assuming the series length is n)
※Write the virtual code first and then analyze it
[1] What is the time complexity of deleting a node with data content 5?
[2] What is the time complexity of deleting the mth piece of data in the series?
[3] Known node p, delete the time of the next node of node p
What is the complexity?
