Python pythagorean triples: In the previous article, we have discussed about Program to Print Collatz Conjecture for a Given Number in C++ and Python. Let us learn Program to Determine all Pythagorean Triplets in C++ Program.

A Pythagorean triplet is a collection of three positive numbers, a, b, and c, such that a^2 + b^2 = c^2. Some things you have to notice while reading.

Find all Pythagorean triplets in the given range in C++ and Python

Pythagorean triples c program: A simple solution is to use three nested loops to generate these triplets that are less than the provided limit. Check if the Pythagorean condition is true for each triplet; if so, print the triplet. This solution has a time complexity of O(limit3), where ‘limit’ is the stated limit.

An Efficient Solution will print all triplets in O(k) time, where k is the number of triplets to be printed. The solution is to apply the Pythagorean triplet’s square sum connection, i.e., addition of squares a and b equals square of c, and then represent these numbers in terms of m and n.

For every choice of positive integer m and n, the formula of Euclid creates Pythagorean Triplets:

a=m^2 -n^2

b= 2 * m * n

c= m ^2 +n^2

Below is the implementation of efficient solution in C++ and Python:

1)Finding all Pythagorean till the given limit in Python

Approach:

  • Scan the upper limit or give static input and save the variable.
  • Calculate the Pythagorean triplets using the formula with a while loop and for loop.
  • If the c value exceeds the upper limit, or if a number equals 0, break from the loop.
  • Print down all Pythagorean triplets’ three numbers.
  • Exit of program.

Below is the implementation:

# enter the upper limit till you find pythagorean triplets
upper_limit = 63
n3 = 0
a = 2
print("printing the pythagorean triplets till the upper limit", upper_limit, ":")
while(n3 < upper_limit):
    for b in range(1, a+1):
        n1 = a*a-b*b
        n2 = 2*a*b
        n3 = a*a+b*b
        if(n3 > upper_limit):
            break
        if(n1 == 0 or n2 == 0 or n3 == 0):
            break
        print(n1, n2, n3)
    a = a+1

Output:

printing the Pythagorean triplets till the upper limit 63 :
3 4 5
8 6 10
5 12 13
15 8 17
12 16 20
7 24 25

Explanation:

The upper limit / input should be entered by a user as static, and stored in a variable.
The value of Pythagorean triplets using the formula is used during and for loops.
The loop breaks out if the value of a side is greater than the upper boundary, or if one side is 0.
The triplets will then be printed.

2)Finding all Pythagorean till the given limit in C++

Approach:

  • Scan the upper limit using cin or give static input and save the variable.
  • Calculate the Pythagorean triplets using the formula with a while loop and for loop.
  • If the c value exceeds the upper limit, or if a number equals 0, break from the loop.
  • Print down all Pythagorean triplets’ three numbers.
  • Exit of program.

Below is the implementation:

#include <bits/stdc++.h>
using namespace std;
int main()
{

    // enter the upper limit till you find pythagorean
    // triplets
    int upper_limit = 175;
    int n3 = 0;
    int a = 2;
    cout << "printing the pythagorean triplets till the "
            "upper limit"
         << upper_limit << ":" << endl;
    while (n3 < upper_limit) {
        for (int b = 1; b <= a; b++) {
            int n1 = a * a - b * b;
            int n2 = 2 * a * b;
            n3 = a * a + b * b;
            if (n3 > upper_limit)
                break;
            if (n1 == 0 or n2 == 0 or n3 == 0)
                break;
            cout << n1 << " " << n2 << " " << n3 << endl;
        }
        a = a + 1;
    }
    return 0;
}
