Finding the Maximum Element
Iterative and recursive way of finding the maximum among all the node's data.
int maximum(struct node *ptr) {
// Variable to keep track of maximum element
// Initialise with INT_MIN
int max = INT_MIN;
while (ptr != NULL) {
// Change max value is current data is greater
if (ptr -> data > max) {
max = ptr -> data;
}
ptr = ptr -> next;
}
return max;
}
int maximum(struct node *ptr) {
int max;
if (ptr == NULL) {
return INT_MIN;
}
max = maximum(p -> next);
return max > p -> data ? max : p -> data;
}
