Implement Program for “Making Change” using Greedy design technique.


#include<stdio.h>
#include<conio.h>
int C[]={1,5,10,25,100};

void make_change(int n);
int bestsol(int,int);

void main()
{
            int n;
            clrscr();
            printf("\n Enter amount you want:");
 scanf("%d",&n);
            make_change(n);
getch();
}


void make_change(int n)
{

            int S[100],s=0,x,ind=0,i;
            for(i=0;i<= 4;i++)
            printf("%5d",C[i]);

while(s!=n)
 {
                         x=bestsol(s,n);
                         if(x==-1)
                        {}
                         else
                         {
                                    S[ind++]=x;
                                     s=s+x;
                        }
 }

 printf("\nMAKING CHANGE FOR %4d\n",n);
 for(i=0;i < ind;i++)
 {
             printf("\n%5d",S[i]);
 }
 printf("\n");
}

int bestsol(int s,int n)
{
 int i;
 for(i=4;i>-1;i--)
            {
                         if((s+C[i]) <= n)
                          return C[i] ;
            }
            return -1;
}

Implement a function of sequential search and count the steps executed by function on various inputs for best case and worst case. Also write complexity in each case and draw a comparative chart.

#include<stdio.h> #include<conio.h> #define size 10 unsigned long count=0; void linear_search(int a[],int no) {       int i;       count++;       for(i=0;i<size;i++)       {                   count++;                   count++;                   if(a[i]==no)                   {                               count++;         ...

Implement functions to print nth Fibonacci number using iteration and recursive method. Compare the performance of two methods by counting number of steps executed on various inputs. Also draw a comparative chart.
