350+Problems / 1000+Solutions 最好不要满足于accept,要追求最高效率。做一题就要杀死一题。leetcode不是给了运行时间的分布吗,基本上每个波峰都代表了一种特定复杂度的算法,中间的起伏体现的就是具体实现细节的差距。每次都要向最前面的波峰努力啊>.<。追逐最前一个波峰的过程不但锻炼算法,还锻炼数据结构,锻炼...

id is the primary key (column with unique values) for this table. Each row of this table contains the score of a game. Score is a floating point value with two decimal places. Write a solution to find the rank of the scores. The ranking should be calculated according to the following ...
We can't remove them, because they might be needed later. This is the first challenge. The problem requests we find all possible solutions, that's the second challenge. It took me lots of time and efforts to put up a long and sloppy solution, which never got accepted. Here the solution...
Example 2:Input: “x=x” Output: “Infinite solutions” Example 3:Input: “2x=x” Output: “x=0” Example 4:Input: “2x+3x-6x=x+2” Output: “x=-1” Example 5:Input: “x=x+2” Output: “No solution” 思路:区分x和数字即可,并把它们解析出来,代码如下: ...
A generic way for solving those calculating numbers problems is to use stack. More specifically, use two stacks: one stack for the operator and the other for the operands. A few caveats Pay attention to the order when popping out operands and calculate, the order matters. ...
