leetcode -- 二進制 在學習編程語言的運算符時,大部分語言都會有與,或等二進制運算符,我在初期學習這些運算符的時候,並沒有重點留意這些運算符,並且在后續的業務代碼中也沒有頻繁的使用過,直到后來的一些算法題目和源碼中經常遇到它們的身影,這些二進制運算符相比普通的運算符具有更快的效率 ...
1個字節它不管怎么樣還是只能表示256個數,因為有符號所以我們就把它表示成范圍:-128-127。它在計算機中是怎么儲存的呢?可以這樣理解,用最高位表示符號位,如果是0表示正數,如果是1表示負數,剩下 ...
前提都是8位的整數表示 -128沒有原碼和反碼(只有補碼) 那么,為什么規定字長8位時-128沒有原碼和反碼呢?下面解釋。 首先看-0,[-0]原碼=1000 000,其中1是符號位,求反操作, ...
