Ask S (n) = A+aa+aaa+aaaa+...+aa. The value of a, where a is a number, and N is the number of bits of a, for example: 2+22+222+2222+22222 (at this time n=5), N and a are all input from the keyboard.#include int main (){int n;int A;int sum = 0;int k = 0;int temp = 1;scanf ("%d,%d", n, a);for (int i = 0; iK = A;temp = 1;for (int j = 0; jTemp *= 10; Once per cycle temp = temp*10;K + = Temp*a; K = K+temp*a}sum + = k;}printf ("%d\n", sum);return 0;}C Langu

Today did a leetcode problem, just beginning is a violent crack, found special judge, very large tree, and then a meal to think, a check, found can use the nature of complete binary tree, and then use the Python to write, Found or not, (this version is to use the height of the left and right children to find, if equal so can directly get the current number of sub-tree nodes,), so continue to think, how to make use of the complete binary tree nature, thought, only need to find the leaf node, the
