publicinthammingWeight2(intn){intcount =0;for(inti=0; i<32; i++) { count += n&1; n = n >>1; }returncount; } 04 第三种解法 上面的两种解法都是拿n和1做与运算,其实还可以换种思路,使用n和n-1做位运算。此时,分两种情况:当n的二进制最后一位是1的时候,n-1的二进制位除了最后一位...
今天介绍的是LeetCode算法题中Easy级别的第45题(顺位题号是191)。编写一个带无符号整数的函数,并返回它所具有的“1”位数。例如: 输入:11 输出:3 说明:整数11具有二进制表示00000000000000000000000000001011 输入:128 输出:1 说明:整数128具有二进制表示00000000000000000000000010000000 ...
Java for LeetCode 191 Number of 1 Bits Write a function that takes an unsigned integer and returns the number of ’1' bits it has (also known as theHamming weight). For example, the 32-bit integer ’11' has binary representation00000000000000000000000000001011, so the function should return 3...
Write a function that takes an unsigned integer and returns the number of ’1’ bits it has (also known as the Hamming weight). For example, the 32-bit integer ’11’ has binary representation 00000000000000000000000000001011, so the function should return 3. 就是检查1的个数,和上一道题leetc...
publicinthammingWeight(intn){intcount=0;while(n!=0){count+=n&1;n>>>=1;}returncount;} 解法二 比较trick的方法,官方题解提供的,分享一下。 有一个方法,可以把最右边的1置为0,举个具体的例子。 比如十进制的10,二进制形式是1010,然后我们只需要把它和9进行按位与操作,也就是10 & 9 = (1010)...
Explanation: The input binary string 11111111111111111111111111111101 has a total of thirty one '1' bits. Note: Note that in some languages such as Java, there is no unsigned integer type. In this case, the input will be given as signed integer type and should not affect your implementation,...
