C. White Sheet There is a white sheet of paper lying on a rectangle table. The sheet is a rectangle with its sides parallel to the sides of the table. If you will take a look from above and assume that the bottom left corner of the table has coordina
/* 思路是判断26个字符在两个字符串中出现的次数是不是都一样,如果一样就返回true. 记住这个方法 */ if (s.length()!=t.length()) return false; int[] words = new int[26]; for (int i = 0; i < s.length(); i++) { words[s.charAt(i)-'a']++; words[t.charAt(i)-'a']--; } for (int i = 0; i < 26; i++) { i
Given two rectangles, find if the given two rectangles overlap or not. A rectangle is denoted by providing the x and y co-ordinates of two points: the left top corner and the right bottom corner of the rectangle. Note that two rectangles sharing a si
判断两整数是否异号: int x, y; //输入比较的两数 bool f = ((x ^ y) < 0); // 返回真,当且仅当x与y异号 说明:当x.y异号,x与y的最高位分别为0和1,取"^"后为1,结果为负数 不用选择语句得到指定整数的绝对值: int v; // 需要得到整数v的绝对值 unsigned int r; // r保存结果 int const mask = v >> sizeof(int) * CHAR_BIT - 1; r = (v + ma
