標籤:override 覆蓋,表示在子類中一個函數覆蓋基類中的同名函數,或者局部的某個函數覆蓋了全域的某個同名函數。被覆蓋的函數通常不能直接被調用,必須藉助一些顯式的強制手段。overload重載,表示在同一級子類中或者同一命名空間中,一個函數因參數類型或個數的不同或傳回型別不同可以有不同的實現。被重載的函數,通常每個不同的實現都可以單獨被調用。hide隱藏,隱藏是override與overload的結合產物下面可以給出一個例子: 1 class A { 2 public: 3 virtual

標籤:DescriptionA straight dirt road connects two fields on FJ‘s farm, but it changes elevation more than FJ would like. His cows do not mind climbing up or down a single slope, but they are not fond of an alternating succession of hills and valleys.
標籤:DescriptionEvery year the cows hold an event featuring a peculiar version of hopscotch that involves carefully jumping from rock to rock in a river. The excitement takes place on a long, straight river with a rock at the start and another rock at
標籤:BearPlays 快速冪題意:給你兩個數A,B,有種操作是將大的數減去小的數,並將小的數乘以2。反覆k次,問你最後的小的數回是多少。題解:由於整個過程$A+B$的值是不會改變的。現在令$S=A+B$,那麼這兩種操作可以看作如下兩種形式: 若$A$是較小的那個數,那麼$A=A*2$ 若$A$是較大的那個數,那麼$A=A-B=A-(S-A)=A*2-S$,由於$S*2>=A*2$,則$A=A*2 mod S$所以我們發現實際上就是計算$A*2^k mod
