[華為機試練習題]42.求二叉樹的深度和寬度,華為二叉樹 題目題目標題:求二叉樹的寬度和深度給定一個二叉樹,擷取該二叉樹的寬度和深度。 例如輸入 a / \ b c/ \ / \d e f g返回3.介面說明 原型: int GetBiNodeInfo(BiNode &head, unsigned int *pulWidth, unsigned int *pulHeight)輸入參數: head
[華為機試練習題]45.求某位元中1的個數,華為練習題 題目描述: 題目標題:求某位元中1的個數。給定一個unsigned int型的正整數,求其二進位表示中“1”的個數,要求演算法的執行效率儘可能地高。詳細描述:原型:int GetCount(unsigned int num)輸入參數: num 給定的正整數輸出參數(指標指向的記憶體地區保證有效):無傳回值:返回1的個數舉例:輸入13,則對應的二進位是1101,那麼1的個數為3個。則:返回3。練習階段: 初級
找出升序數組中和為給定值的兩個數字,升序數組輸入一個已經按升序排序過的數組和一個數字,在數組中尋找兩個數,使得它們的和正好是輸入的那個數字。如果有多對數位和等於輸入的數字,輸出任意一對即可。詳細描述:介面說明原型:bool FindTwoNumbersWithSum(int aData[], unsignedint uiLength, int sum, int *pNum1, int *pNum2
