Chapter 2 Discrete Mathematics for Computer Science
Text A Exercises
1. C48 =70，C38 =56 2. 6*25=192 3. if a=0
then if b=0 then return(0) else return(1+Add(0,b-1)) else if b=0 then return(1+Add(a-1,0)) else return(1+1+Add(a-1,b-1)) 4. if Rest(S)= ?
then return(First(S))
else if (First(S) 5. Now we can define function Concat(S1,S2) as: if(Length(S1)=0) then return(S2) else return(Cons(First(S1), Concat(Rest(S1),S2))) Text B Exercises 1.[Proof]:According to given conditions, we know an = an-1 + 2n an-1 = an-2 + 2(n-1) …… a2 = a1 + 2*2 a1 = 3 sum all items in left side, and delete same items in the right side of equations, we can result that an = 3 + 2（2+3+……+n-1+n）=1+n(n+1)=n2+n+1 that is what we conclude. Text C Exercises 1.（1）depend, dependent (2) correspond, correspondent (3)grow, grown (4)solve, solvent (5) relate, relational (6)recur, recursive (7) validate, valid (8) conclude, conclusive (9) justify, justificative 2.(1)connect-disconnect (2)possible-impossible (3)regular-irregular (4)measure-countermeasure Chapter 3 Algorithms in the Real World Text A Exercises 2. finite, solving, processing, effective, eventually, next, randomly 3. by, in, on, in, on, from 4. the algorithm can terminate. It is correct for sorting. If the length of array A is n, the time for computation is O(n2) Its memory cost n units. As n increase, its computational cost will become large. Text B Exercises 3.(1)—(e), (2)—(c), (3)—(d), (4)—(a), (5)—(b) 4. inconvenience, incapacity, independence 5.We couldn’t have lived without water.
