Question 41
In the backtracking algorithm, if it is determined that a partial solution would end in a dead end, then the algorithm ____.

terminates

restarts
V
removes the most recently added part and tries other possibilities

was designed incorrectly

Question 42

void decToBin(int num, int base)
{
if(num > 0)
{
decToBin(num/base, base);
cout<<num % base;
}
}

Note that inside the recursion decToBin is executed before the cout << ...
, therefore the last digit is printed out last

Given the recursive function above, what is the result of decToBin(39, 2)?

10111

  • Proof of two Legendre Symbol identities

    Similarly to (1), we can find some c in (Z/pZ)* such that the order of c is 5. Then c^5 = 1 (mod p). Then we have c^5 - 1 = (c - 1)(c^4 + c^3 + c^2 + c + 1) = 0 and we get c^4 + c^3 + c^2 + c + 1 = 0 (mod p).

  • Real Analysis : Neighborhoods

    We know g'(c) is the limit of (g(x)-g(c))/(x-c) as x->c. When x>c, x-c>0, but (g(x)-g(c))/(x-c)->g'(c)>0, so we can find some d1>0, such that for all x in (c,c+d1), we have g(x)-g(c)>0.
