Question: Tile Game

In connection to the National Mathematics Day celebration, the Regional Mathematical Scholars Society had arranged for a Mathematics Challenge Event where school kids participated in large number. Many interesting math games were conducted, one such game that attracted most kids was the tile game where the kids were given 'n' square tiles of the same size and were asked to form the largest possible square using those tiles.

Help the kids by writing a program to find the area of the largest possible square that can be formed, given the side of a square tile (in cms) and the number of square tiles available.

Input Format:
First line of the input is an integer that corresponds to the side of a square tile (in cms).
Second line of the input is an integer that corresponds to the number of square tiles available.

Output Format:
Output should display the area of the largest possible square that can be formed (in square cms) with the available tiles.
Refer sample input and output for formatting specifications.
[All text in bold corresponds to input and rest corresponds to output.]

Sample Input and Output :
Enter the side in cm of a square tile
5
Enter the number of square tiles available
8
Area of the largest possible square is 100sqcm


SOLUTION:
#include<stdio.h>
int main()
{
    int l,n,i=1,m=0,a;
    printf("Enter the side in cm of a square tile");
    scanf("%d",&l);
    printf("\nEnter the number of square tiles available");
    scanf("%d",&n);
    while(i*i <= n)
    {
        m=i*i;
        i++;
    }
    a=m*(l*l);

Question: Lucky Gifts

"Planet Kids Entertainment Fair" is back to delight kids and parents. The Fair will have non-stop entertainment with an extravaganza of games, exciting rides, sports, art & crafts, role-plays, inspiring competitions, prizes & gifts, and yummy food.

Few lucky attendees at the Fair will be given a pack of candies as a lucky gift and the show coordinator has assigned you the task for choosing the number of attendees who will receive the pack of candies. There are 'N' candies available and you need to decide how many candies to place in each pack. Each pack must contain the same number of candies. You should choose an integer A between 1 and N, inclusive, and place exactly A candies into each pack. You should make as many packs as possible but since you enjoy eating candies very much, you eat the remaining candies.

Write a program that will calculate the maximum number of candies per pack that can be made with 'N' candies so that you can also maximise the number of  candies that you can eat.

Input Format:
The first and only line of input contains an integer N.
