Then use this table to find the number of ones in each byte of the integer and sum them to get total number of set bits in an integer. Here, we take the size of integer by sizeof operator and iterates the loop maximum for sizeof(int) times. While counting the set bits we iterate...
Initially, we declare the function that will return the number of set bits in an integer. The function will have one parameter , which will represent the given number to count its set bits.First, we declare the to store the number of set bits. Second, while the given number is greater ...

我很好奇,由BitTwiddling Hacks指出,与简单的Lookup Table方法相比,该算法的性能要好得多...现在,我想,也许我的一点研究对其他人也很有趣... PS:并行计数算法大约是35在我的计算机上平均比simpel LUT解决方案快%。 这也很好地显示了与人脑兼容的解决方案与二进制机器

Count the number of bits set to 1 in mask. This count is the number of unique digits. The time complexity is also the same as the above solutions. 6. Conclusion This article provided different ways to count the number of unique digits in an integer, along with their time complexities. ...
