I can't imagine a useful reason to have a recursive function to find this, but here you go:
int sumEvens(int start, int end) {
// end condition
if (start > end) {
return 0;
}
// correction if we start on an odd number
if (start % 2 == 1) {
return sumEvens(start + 1, end);
}
// actual work
return start + sumEvens(start + 2, end);
}
Invoke with sumEvens(2, 50) to get the sum of all even numbers in the range [2,50]

The efficiency of using recursive function rather than using ordinary function?
For some algorithms recursive functions are faster, and there are some problems that can only be solved through recursive means as iterative approaches are computationally infeasible.
How do you write a C program to find the GCD of two given integers using non recursive functions?
Use the following function: int gcd (int a, int b) { while (b != 0) { a %= b; a ^= b ^= a ^= b; } return a; } Note that a ^= b ^= a ^= b is an efficient method of swapping two values.

How do you write a program to factorial in PHP?
To write a program that calculates the factorial of a number in PHP, you can use a recursive function or an iterative approach. Here’s a simple example using a loop: function factorial($n) { $result = 1; for ($i = 2; $i <= $n; $i++) { $result *= $i; } return $result; } echo factorial(5); // Outputs: 120 This code defines a function that multiplies numbers from 2 up to the given number $n to compute the factorial.

How do you put a recursive equation into a ti-84 calculator?
To input a recursive equation into a TI-84 calculator, you can use the "Seq" function. First, access the "Y=" menu, then define your recursive sequence by using the format Seq(Y1, n, start, end), where Y1 is your recursive formula, and "start" and "end" are the range of values for n. Alternatively, you can manually calculate the terms by iterating through the recursive formula using the calculator's programming feature or list functions.

Is BFS recursive?
No, Breadth-First Search (BFS) is not inherently recursive. It is typically implemented using a queue data structure rather than recursion.
