element to an array, you need to move a large number of elements, empty the space of an element in memory, and then put the added elements in it. Similarly, if you want to delete an element, you also need to move a large number of elements to fill out the moved element. An array should be used if the application requires fast access to the data, with little or no elements inserted and removed. The list is reversed, and the elements in the list are not stored sequentially in memory, but are link

[Problem description](1) For an integer N, write a function f (n) so that it returns the number of '1' in all natural numbers between 1 and N (expressed in decimal number. For example, for n = 13, natural numbers 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, '

corresponding problems, get the output or implement process control by obtaining the object status information. 5. What is the purpose of const?

Problemconsider a function which, for a given whole number N, returns the number of ones required when writing out all numbers between 0 and N. for example, F (13) = 6. notice that F (1) = 1. what is the next largest N such that F (n) = n? Algorithm idea: calculate the number of 1 in each number cyclically. If F (n) =
