You are given an arraycoordinates,coordinates[i] = [x, y], where[x, y]represents the coordinate of a point. Check if these points make a straight line in the XY plane. Example 1: Input: coordinates = [[1,2],[2,3],[3,4],[4,5],[5,6],[6,7]] Output: true Example 2: In...
If you want a challenge, please do not see below and ask yourself what are the possible input cases. 实现atoi将字符串转换为整数。提示:仔细考虑所有可能的输入情况。如果你想要挑战,请不要看下面,问问自己可能的输入案例是什么。 Notes: It is intended for this problem to be specified vaguely (ie,...
This is an invalid board that you will not receive – as battleships will always have a cell separating between them. Follow up: Could you do it in one-pass, using only O(1) extra memory and without modifying the value of the board? 【解答】要数有多少 battleship,并且要求使...
Your function should return length =2, with the first two elements ofnumsbeing1and2respectively. It doesn't matter what you leave beyond the new length. 第一次提交以为要缩短原向量长度,仅保留由不同数字组成的向量,用到STL中vector的erase(iterator front,iterator last)方法,删除两个迭代器[front,las...
