Hey @dhanshree_p18

int countSetBits(int a, int b){
	int ans=0;
	for(int i=a;i<=b;i++){
        int j=0;//added this
		while( i>>j ){ //updated this
			ans +=((i>>j)&1); //updated this
			j++;//updated this
		}
	}
	return ans;
}

Earlier u are making i=0 again in every iteration hence giving runtime error
