For each of the following recursive methods, identify the base case, the general case, and constraints on the argument values, and explain what the method does.

A.

int power (int base, int exponent)

{

if (exponent == 0)

return 1;

else

return (base * power(base, exponent -1));

}

B.

int recur (int n)

{

if (n< 0)

return -1;

else if (n < 10)

return 1;

else

return (1 + recur(n / 10));

}
