Functions are a bunch of statements glued together. A function is provided with zero or more arguments, and it executes the statements on it. Based on the return type, it either returns nothing (void) or something. A sample syntax for a function is

return_type function_name(arg_type_1 arg_1, arg_type_2 arg_2, ...) {

...

...

...

[if return_type is non void]

return something of type `return_type`;

}

For example, a function to read four variables and return the sum of them can be written as

int sum_of_four(int a, int b, int c, int d) {

int sum = 0;

sum += a;

sum += b;

sum += c;

sum += d;

return sum;

}

You have to write a function int max_of_four(int a, int b, int c, int d) which reads four arguments and returns the greatest of them.

+= : Add and assignment operator. It adds the right operand to the left operand and assigns the result to the left operand.

a += b is equivalent to a = a + b;

Input Format

Input will contain four integers - , one in each line.

Output Format

Print the greatest of the four integers. PS: I/O will be automatically handled.

/*

Add `int max_of_four(int a, int b, int c, int d)` here.

*/

int main() {

int a, b, c, d;

scanf("%d %d %d %d", &a, &b, &c, &d);

int ans = max_of_four(a, b, c, d);

printf("%d", ans);

return 0;

}
