Note the two applications of VP[SUBCAT=?rest] -> VP [SUBCAT= [HEAD=?arg, TAIL=?rest]] ARG [CAT=?arg]. Also note the topmost VP has [SUBCAT=nil], which is needed to apply the rule with left-hand side S. How the rules for subcategorisation are applied is illustrated in Figure 1. In order to handle the verbs in our example sentences, further rules for V and ARG are needed, but it should be possible to reuse the rule VP[SUBCAT=?rest] -> VP[SUBCAT= [HEAD=?arg, TAIL=?rest]] ARG[CAT=?arg] for several verbs, regardless of their subcategorisation frames.

2. The function f is defined for non-negative integers a and b recursively as follows: f (а, b) 3D1 if a = 0 or b = 0 f (a - 1, b f (a f (а, а) 1) + 2a - 1 if a if a > b if a < b b b, b) + f (b, b) + f (b а, а) } Compute f (2, 3) by drawing a recursion tree showing all of the computation required and then use your tree to compute the answer.
Consider the following recursive function to compute factorialint fact (int n) {if (n <= 1)return 1;elsereturn n * fact(n-1);}int main() {cout << fact(5) << endl;return 0;} Show the stack of activation records each time the function fact is called (either directly or recursively). Each activation record needs to be identified by the name of the function and the parameter value, but there is no need to elaborate the specific content of each activation record.
