## BEECROWD 1074 Even or Odd Solution in C,C++,Python

BEECROWD 1074 Even or Odd question

Welcome to our comprehensive guide on how to solve the “BEE CROWD 1074 Even or Odd ” problem using C++, C and Python. In this article, we will explain the solution to the Even Square problem, how to write code in C++, C and Python, and how to optimize the code for maximum performance.

### Problem Description

The Even Square problem requires us to find the sum of the squares of even numbers between two given numbers, inclusive. For example, given the input range [2,10], the program should output 220, which is the sum of the squares of the even numbers between 2 and 10 (i.e., 2^2 + 4^2 + 6^2 + 8^2 + 10^2).

### Solving the Problem in C++

C++ is a popular language used for competitive programming and algorithmic problem-solving. Solving the Even Square problem in C++ involves iterating over the given range of numbers, checking if the current number is even, squaring the number if it is even, and adding it to a running total. Here’s the C++ code to solve the Even Square problem:

#include <iostream> using namespace std; int main() { int a,n; cin>>n; for(int i=0;i<n;i++) { cin>>a; if(a>0) { if(a%2==0) cout<<"EVEN POSITIVE"<<endl; else cout<<"ODD POSITIVE"<<endl; } else if(a<0) { if(a%2==0) cout<<"EVEN NEGATIVE"<<endl; else cout<<"ODD NEGATIVE"<<endl; } else cout<<"NULL"<<endl; } return 0; }

## Solving the Problem in C

C is another popular language used for competitive programming and algorithmic problem-solving. The Even Square problem can be solved in C using the same logic as in C++. Here’s the C code to solve the Even Square problem:

#include <stdio.h> int main() { int a, b, sum = 0; scanf("%d %d", &a, &b); for(int i = a; i <= b; i++) { if(i % 2 == 0) { sum += i * i; } } printf("%d\n", sum); return 0; }

### Solving the Problem in Python

Python is a popular language used for data science, machine learning, and algorithmic problem-solving. The Even Square problem can also be solved in Python using a similar loop-based approach. Here’s the Python code to solve the Even Square problem:

a, b = map(int, input().split()) sum = 0 for i in range(a, b + 1): if i % 2 == 0: sum += i * i print(sum)

### Performance Optimization

While the above code solutions are straightforward, there are a few tips and tricks that can be used to optimize the performance of the code. Here are some ways to optimize the code:

### Using bitwise operations instead of modulo operator

Instead of using the modulo operator to check if a number is even, we can use bitwise operations. For example, to check if a number is even, we can use the following code: `if((i & 1) == 0)`
