Die (' 1 ') Die () and exit () are all abort script execution functions; the two names of Exit and die refer to the same function, and die () is the alias of the exit () function. The function accepts only one parameter, either a value returned by a program or a string, or a parameter without input, and the result has no return value.Reference: Although the two are the same, there are usually subtle selectivity in use.When passed to the exit and Die f
Before encountering a very interesting topic, is about the problem of sorting algorithm:Known: An array: array element: 0 or 1 or 2Solve: Sort the array by 0-1-2?1Template classT>2 voidSwap (t t1, tT2)3 {4T tmp =T1;5T1 =T2;6t2 =tmp;7 }8 9 //sorting a array which the elements is 0
http://www.51nod.com/onlineJudge/questionCode.html#!problemId=1393The method is fascinating. Also looked at other people's thinking to come out.First consider turning 0 all into-1. Then a prefix is counted and expressed in sum[i].Then the substring starting from the starting point is valid as long as the value of Sum[i] equals 0.If the substring starting point is

01 the problem of obtaining and not obtaining a backpack is actually an opportunity cost problem. If you take something, although the current value has increased for the moment, you have paid the opportunity cost. If not, the space left may be more valuable in the future. Therefore, space and value are always in conflict. Our goal is to use limited space to load the best value.
