Download Solution PDFConsider the following ANSI C function:
int SomeFunction (int x, int y)
{
if ( (x == 1) I I (y == 1)) return 1;
if (x == y) return x;
if (x > y) return SomeFunction(x - y, y);
if (y > x) return SomeFunction(x, y - x);
}
The value returned by SomeFunction(15, 255) is _______.

Explanation :
SomeFunction( x, y )
|
{ y > x (255>15) } { again y > x (240 > 15) } |
|
{ again |
y > x }And so on there will be situation when both x and y become equal.
SomeFunction(15, 15 ) -> { return x; } so 15 will be returned.
Note :
- In case , If you wondering why call to SomeFunction(15 ,15) will be made? Why this particular call will be in execution flow?
- because , we encountered SomeFunction(15, 225) and 152 == 225 ; and we are subtracting 15 from variable y ( y=225)
