SELECTION SORT: #include<stdio.h> #include<conio.h> #include<math.h> #include<time.h> #define n 10000 void selection_sort(int[]); unsigned long int count=0; void main() {             int a[n];             int choice,i;             clrscr();             printf("1.Sorted Data  2.Random Data \n");             scanf("%d",&choice);             switch(choice)             {                         case 1:    ...

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. (Fibonacci series 1, 1, 2, 3, 5, 8…..  Here 8 is the 6th Fibonacci number) #include<stdio.h> #include<conio.h> int iteration(int); int recursive(int); int count=0; void main() { int n,choice,ans; clrscr(); printf("\nenter nth number : "); scanf("%d",&n); printf(“\n==iteration==”); ans=iteration(n); printf(“\nans=%d\ncount=%d”,ans,count); printf(“\n\n==recursive==”); ans=recursive(n); printf("\nans=%d\ncount=%d",ans,count); getch(); } int iteration(int n) { int f=1,s=1,t,i; count++;   count++; for(i=3;i<=n;i++) { t=f+s; count++; f=s; count++; s=t; count++; } count++; return t; } int recursive(int n) { count++; if(n==0 || n==1) { cou...

Implement program for randomized version of quick sort and compare its performance with normal version of quick sort using steps count on various number of inputs.

RANDOMIZED QUICK SORT: #include<stdio.h> #include<conio.h> #define size 10 unsigned long count=0; void randomized_quick(int a[],int low,int high) {       int pivot;       count++;       count++;       if(low<high)       {                   count++;                   pivot=randomized_part(a,low,high);                   count++;                   randomized_quick(a,low,pivot-1);                   cou...
