Dividetwo integers without using multiplication, division and mod operator.如果可以用乘的话,二分搜索倒是不错的解法。否则,只能寄希望于位符操作了。基本思想就是把除数向左移位(×2)然后与被除数比较,直到发现仅次于被除数的那... leetcode ide

Divide Conquer Combine 分治法的基本思想是将将一个问题分解成若干个规模更小的子问题,然后依据子问题的解得到原问题的解 这个需要递归解决问题,递归解决的子问题一定要与原问题的结构形式保持一直,如果不能一致,需要变成一致 递归函数传递的参数不能是常数 归并算法和快排都是分治 两个n位数的乘积也能分治,将两...
Using divide and conquer approach, the problem in hand, is divided into smaller sub-problems and then each problem is solved independently. When we keep dividing the sub-problems into even smaller sub-problems, we may eventually reach a stage where no more division is possible. Those smallest ...

ThomasIn this dissertation, we introduce an efficient VLSI array architecture for binary multiplication, and discuss its extension for vector-scalar multiplication. The architectures are based on an existing parameterized divide and conquer algorithm that uses optimal partitioning and redundancy removal for ...
A novel VLSI array architecture for vector-scalar multiplication is introduced. It is based on a parameterized divide and conquer algorithm that uses optimal partitioning and redundancy removal for simultaneous computation of partial sums. Two variations of the proposed Parameterized Vector-Scalar ...
