fibanocci with one RECURSIVE CALL only

Posted on by cs daixie

通常fibanocci要两个递归调用  复杂度o(2^n)

但是用指针的话，可以只用1次call   复杂度 o(n)

(10 minutes) Write a program called fib.c that calculates the nth fibanocci

number. The equation for the Fibonacci numbers is defined as follows:

Fib(0)=0

1.
Fib(N)=Fib(N−1)+Fib(N−2)

  1. Name your executable fib.out
  2. Your program should accept N as a command line argument
  3. You MUST solve this program RECURSIVELY
  4. Unlike the example in class, you may only have ONE RECURSIVE CALL in

    your function

    1. Hint pointers help make this possible.

  5. Here are the first 100 numbers in the Fibonacci sequence
  6. Examples

    1../fib.out 0
    The 0th fibanocci number is 0.

    2../fib.out 1
    The 1th fibanocci number is 1.

    3../fib.out 10
    The 10th fibanocci number is 55.

C++ class repositioned items

Posted on by cs daixie

In many applications, the order of the data items in a list changes over time. Not only are new data items added and existing ones removed, but data items are repositioned within the list. The following operation is needed to move a data item to the beginning of an array. Do not use a vector for this assignment.

Precondition: the array is not empty.

Postcondition: This function removes the data item marked by a cursor from an array and reinserts the data item at the beginning of the array.

A cursor is some indicator for the element to be moved.  It may be an index number or a search key.  For example, the function could take in the index number 4 to move the fifth element of the array to the front.  Alternatively, the function could take in the search string “Joe” and if found in the array, that “Joe” element would be moved to the front.  You can select the strategy you prefer for the cursor.

Minimum Requirements:

  • Create a class that has an arra

代写C++作业，实现多线程BFS搜索

Introduction

In this assignment you will perform a parallel breadth-first search (BFS) of the 4×3 Sliding Tile state space. The result of this search will be that the distance of every state in the state space from the initial configuration will be stored in an array. In C++ you can only access items in an array using an integer offset. Thus, we cannot directly map between our Sliding Tile puzzle class and an element in the depth array. Luckily, there is a 1-to-1 mapping between states in the puzzle and integers between 0 and 12!/2. We can perform this mapping using what are called “Ranking” and “Unranking” functions. A ranking function will convert a state into an integer, and an unranking function will convert an integer into the corresponding state. T
