We are building EduLadder(ELADR) - Protocol

The Eladr Protocol is a decentralized, security and efficiency enhanced Web3 noSQL database powered by IPFS as the data storage layer https://ipfs.io/, and the Cardano block chain as the rewards token platform, https://cardano.org/. It provides a JSON based, IPFS layer 2 solution for data indexing and retrieval in an 'append only' file system built with open source Node.js API libraries.

The ELADR token was designed to incentivize and reward community members as a proof of contribution. Token holders are also granted access to EduLadder.com premium features as well as associated ELADR token enabled apps.

1. Sort a given set of elements using the Quicksort method and determine the time required to sort the elements. Repeat the experiment for different values of n, the number of elements in the list to be sorted and plot a graph of the time taken versus n. The elements can be read from a file or can be generated using the random number generator.

# include <stdio.h>
# include <conio.h>
# include <time.h>
void Exch(int *p, int *q)
int temp = *p;
*p = *q;
*q = temp;
void QuickSort(int a[], int low, int high)
int i, j, key, k;
key=low; i=low+1; j=high;
while ( a[i] <= a[key] ) i=i+1;
while ( a[j] > a[key] ) j=j-1;
if(i<j) Exch(&a[i], &a[j]);
Exch(&a[j], &a[key]);
QuickSort(a, low, j-1);
QuickSort(a, j+1, high);
void main()
int n, a[1000],k;
clock_t st,et;
double ts;
printf("\n Enter How many Numbers: ");
scanf("%d", &n);
printf("\nThe Random Numbers are:\n");
for(k=1; k<=n; k++)
QuickSort(a, 1, n);
printf("\nSorted Numbers are: \n ");
for(k=1; k<=n; k++)
printf("%d\t", a[k]);
printf("\nThe time taken is %e",ts);
