Description Inexperienced in the digital arts, the cows tried to build a calculating engine (yes, it's a cowmpouter) using binary numbers (base 2) but instead built one based on base negative 2! They were quite pleased since numbers expressed in base…

题目链接 题意 : 将一个10进制整数转化为-2进制的数. 思路 :如果你将-2进制下的123转化为十进制是1*(-2)^2+2*(-2)^1+3*(-2)^0.所以十进制转化为-2进制就是一个逆过程.找到最小的非负整数x使得当前数减x能被2整除,这个x将作为新的最高位写到结果中,然后当前数减去x再除以-2,貌似在这里不能严格的说是余数,因为负数的余数不太准确. //POJ 3191 #include <stdio.h> #include <string.h> #include &…
