Consider the following function: int recEx13(int x) { if (x return 0; else if (x == 1) return 2; else return (recEx13(x - 1) + recEx13(x - 2) + recEx13(x - 3)); } What is the output of the...

Consider the following function:

int recEx13(int x)

{

if (x

return 0;

else if (x == 1)

return 2;

else

return (recEx13(x - 1) + recEx13(x - 2)

+ recEx13(x - 3));

}

What is the output of the following statements? (4, 6)

a. cout <><>

b. cout <><>

c. cout <><>

d. cout <>

Consider the following recursive function:

void recFun(int x, int y)

{

if (x > 0 && y > 0)

{

if (x >= y && y != 0)

{

cout <><>

recFun(x - y, y);

}

else if (y > x && x != 0)

{

cout <><>

recFun(y - x, x);

}

}

Else

cout <>

}
