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.
Algorithm can be defined as an interpretable, finite set of instructions for dealing with contigencies and accompanying task that has recognizable end-points for given inputs. It is a tool for solving a well computational problem. A recursive algorithm is one which calls itself.
A recursive function is one that calls upon itself until a given result in the original call is met. Take a look at this example. Program Recursion; Uses crt; Var number:longint; Function Factorial(number:longint):longint; Begin if number > 0 then factorial:=number*factorial(number-1) else factorial:=1; End; Begin clrscr; readln(number); writeln(factorial(number)); readln; End. Note how the function factorial calls itself.

Some problems cry out for recursion. For example, an algorithm might be defined recursively (e.g. the Fibonacci function). When an algorithm is given with a recursive definition, the recursive implementation is straight-forward. However, it can be shown that all recursive implementations have an iterative functional equivalent, and vice versa. Systems requiring maximum processing speed, or requiring execution within very limited resources (for example, limited stack depth), are generally better implemented using iteration.
Basically, it has two major functions: store data to a given address and retrieve data from a given address.

To find the sum of integers in a square grid that match a given value, add up all the matching integers in the grid.
It is often possible to find an explicit formula that gives the same answer as a given recursive formula - and vice versa. I don't think you can always find an explicit formula that gives the same answer.
The recursive approach for finding the longest increasing subsequence in a given sequence involves breaking down the problem into smaller subproblems and solving them recursively. This method involves comparing each element in the sequence with the previous elements to determine the longest increasing subsequence.

Use a pseudo-random number generator to produce random integers. To determine if a given integer is odd or even, use the following functions: bool is_odd (int x) { return x%2; } bool is_even (int x) { return !is_odd (x); }
Two consecutive integers will be 0.5 more and 0.5 less than the quotient of their sum divided by 2. The given sum of the two consecutive integers divided by 2 is -3471.5, so the two consecutive integers are -3472 and -3471.
1 No. 2 No. 3 Yes.
17 including the two numbers given.
Sum = 306.
You cannot. If the ratio gives x and y as the integers then so also are 2x and 2y, or 3x and 3y and so on.
