Hi I need help describing the time complexity and run time of the following code.

/* in the worst case scenario: what is the value of count for an input.
value of 'n'? */
public static int pw (int n) {
count++;
if(n== 0) {
return 1;
// note count is global and init'd to 0.
}
return pw (n-1) + pw (n-1);
}
/* is the above method considered 'divide and conquer'? Why or why not?
How would you describe the run-time of the above code? */
