1010 derivation of unary polynomial Design function to find the derivative of unary polynomial. (note: the first derivative of x ^ n (n is an integer) is nx ^ n (n-1).) input format: enter polynomial non-zero coefficients and exponents in an exponent...
binary tree is used for sorting, searching, and so on. Multi-tree is mainly used for files and databases, because of its small height, it can reduce the number of disk io. so the question is, since multi-tree is so good, why not replace the application...
use JavaScript to build a segment tree, and recursion is used in the construction process. This should make the call stack overflow. I wonder if there is any other way to solve this problem. < H1 > Code < H1 > ...
enter two integer sequences, the first representing the push-in order of the stack, and the second indicating whether it is the pop-up order of the stack. It is assumed that all the numbers pressed are not equal. for example, stack pressing order: 1. T...
