Nptel Week - 1(Assignment-1)

Write a program to find the number of perfect squares between given two numbers A and B (both inclusive). A number is called a perfect square if it can be written as x*x for some integer x.

Constraints:

Both A and B are positive. They both are less than 100,000.

Input: Two numbers A and B separated by a space

Output: Count of the number of perfect squares

Example 1:

Input: 3 10

Output: 2

Example 2:

Input: 16 70

Output: 5

#include<stdio.h>
int main()
{
  int a,b,i,d=0;
  
    scanf("%d",&a);
    scanf("%d",&b);
    for(i=1;i<=b;i++)
  {
    if((i*i)>=a && (i*i)<=b)
        d++;
  }
  printf("%d",d);
return 0;
