C++ :: Program That Uses Recursion To Find Longest Increasing Sequence From A Grid In File
Mar 25, 2013
Any examples of a c++ program that uses recursion to find the longest increasing sequence from a grid in a file. Like
2 4 6 8
10 12 14 16
18 20 22 24
I have to use a structure named Point and a structure named Sequence.
const int MAXROWS = 4;
const int MAXCOLS = 4;
const int MAXFILENAME = 255;
// Structure used to define a point (x,y) in the grid.
typedef struct {
int x, y;
The following is a part of a hailstone cpp program. I want to write an option to let users enter 2 numbers and the program evaluates the longest sequence the number has within the 2-number range and return the count.
Code: int longestHailstoneSequenceLength(int start, int end) { int max = 0; int s= start; while (s!=1)
Currently I am working on a program that will find the actual distance between two points on a grid. It also determines the angle of the line segment in degrees. Now, i need it to be able to find any other points on or near the line. It will be running in a loop to find each additional point sequentially until all the points have been plotted. Unfortunately, I am not entirely sure how this is done. So far, I think that I could develop an algorithm that converts the angle into a ratio of vertical movements to horizontal ones.
I am trying to make a program into which you writre for example ten Names or words or etc. and it would find the longest name/word write it and the numbers of characters too but I have problem with displaying that name. Here is me source code, the problem is here "vitaz=szInput;" i don't know how to save that longest name/word.
#include <cstdlib> #include <iostream> #include <string.h> using namespace std; int main () { char a; char szInput[256],vitaz[256];
Write a program to read in a sequence of examination mark from a text file named as input.txt and produce the mean, and standard deviation of the marks. Your program should also produce a bar chart for each grade where the range of mark is given as below.
GradeMarks Range A80-100 B70-79.9 C50-69.9 D40-49.9 F0-39.9
Output the result to another text file named as output.txt.
I have to made a programme which will search for given number and it must work in O(log(n)). The problem is that this programme beside finding this number have to find how many times this given number is used in this sequence.
Sequence is from lowest to highest only one possibility to use binary search algorithm
For example when we have squence -1 -2 3 3 3 3 4 5 6 7 7 8 9 9 9 9 10
The numbers we need to search are 1 , 3 , 7 , 9 , 11 , 12
The answer is 0 , 4 , 2 , 4 , 0 , 0
So we need to find the sum of used number in sequence.
I have written algorithm Code: int start = 0; int end = sequencelenght - 1; int mid = 0; /// Binary serach while (start<=end) { int mid=(start+end)/2; if (sequence[mid]==givennumber) {
[Code] .....
As u see i search for given numer with binary with O(log(n)) but when i have to sum the duplicates the only good way i see is using loop to right and left but this have got log(n) specification (because when sequence would be for example 7 7 7 7 7 7 7 7 7 and given number to search will be 7 this will be O(n) loop).
How would look the most optimal algorithm look for this exercise? I mean O(log(n)) the fastest algorithm....
I found this implementation on a website for printing the longest common subsequence. But it gives wrong answers for some reason even though the code seems right to me.
Here is the code:
#include <iostream> int lcs(char *X, char *Y, int m, int n) { int L[m+1][n+1]; for(int i = 0; i<=m; i++)
Write a menu driven program that will fill grid with values between 1 and 100. Begin the program by declaring a array of type int. Then present the user with the following menu
Enter 1 to add Enter 2 to edit Enter 3 to delete Enter 4 to search Enter 5 to display Enter 0 to Quit
Each item of the menu must be implemented as a function. The program should Only allow values between 1 and 100
Always ask the user to apply coordinates for the cell to be changed
Flag an error when try to delete or edit a cell with a zero (0)
Flag an error when try to add to a cell that is not blank
Display the complete and nicely formatted grid when option 5 is selected
c++ program that reads in a sequence of binary digits (values 0 and 1) and stores them into a STL container. The input should terminate on any input that is not a 0 or 1. After finishing the read-process, apply a "bit-stuffing" algorithm to the container. In this case the bit stuffing should occur after four consecutive bits of the same value.i,e. four 0's or four 1's.. Also write the de-stuffing code to process the stuffed data to recreate the original data and verify that the original data is recovered correctly.
I wrote this code to search words in the file and display if the program found the word or not. when i write the words in the file on the same line (without the endl) like this :
w_toFile << "gilbert"; w_toFile << "lara"; w_toFile << "rana"; i can search any word.
but when i write them with the endl, the program can find only the first word. what can i do to make the program find any word even if they are each on a line?
here is the full code:
#include <iostream> #include <windows.h> #include <fstream> #include <string> using namespace std; int main (void) { string wordsearch;
It seems that boost's file recursion requires that the file using the recursion must be in the include path. This makes using file recursion in a library header a problem as libraries may be located in a subdirectory of an include path (which is minor since the programmer can state the subdirectory in the recursive file call as long as it is not relative to the calling file). I also found it a problem when the main compile directory isn't in the compile path.
Im having trouble on getting the quantity up of the variable "item.iqty". For example the current quantity is 5 and in this function, the user inputs a number and it should add to the variable "item.iqty". So if if the user inputs 2 then the current quantity should be 7 now but in my program it hasnt changed. its still 5
I'm trying to implement a linked list using my own node class. I've created functions to add to the head and tail, return the size of the linked list as well as the value stored within the current pointer.
However, my problem is that when I wrote a test program to see whether my list worked, my list did not appear to increase in size past 1 item in the list.
this is the test program I wrote:
int main() { int counter, data; linkedlist *my_list = new linkedlist(); cout << my_list->size() << endl; for (counter = 0; counter < 5; counter++) {
[Code] ....
I'm sure it's probably something simple that I've overlooked . But I'm still relatively new to the concept of dynamic memory allocation.
