Simple C program to solve Tower of Hanoi problem for n disks using recursion.

Code:

#include <stdio.h>

#include<conio.h>



void tower(int n, char from, char to, char through){

if (n==1){

printf("\n Move disk 1 from rod %c to rod %c", from, to);

return;

}

tower(n-1, from, through, to);

printf("\n Move disk %d from rod %c to rod %c", n, from, to);

tower(n-1, through, to, from);

}



main(){



int n;

clrscr();

printf("Enter the number of disk: ");

scanf("%d",&n);

tower(n, 'A', 'C', 'B');

getch();

}

Simple Java program to Implement sorting algorithm using TCP on Server application Input: Give input on client side and client should receive sorted output from server and display sorted list on input(client) side. Note: You can implement any sorting algorithm by changing the sorting algorithm code on server side Code: Server: package aj.pkg7; import java.io.*; import java.net.*; import java.util.*; class Server { public static void main(String args[]) throws Exception { ServerSocket ss=new ServerSocket(1111); Socket s=ss.accept(); DataInputStream din=new DataInputStream(s.getInputStream()); DataOutputStream dout=new DataOutputStream(s.getOutputStream()); int r,i=0; int n=din.readInt(); int a[]=new int[n]; System.out.println("data:"); int count=0; for(i=0;i<n;i++) { a[i]=din.readInt(); } int number = a.length; for (int i1 = 0; i1 < number-1; i1++) for (int j1 = 0; j1 < number-i1-1; j1++) if (a[j1] > a[j1+1]) { int temp = a[j1]; a[j1] = a[j1+1]; a[j1+1] = temp; } ...
