1.两数相加 递增的正整数序列中,如{1、2、3、4、5、6}中找出满足两个数相加之和为M=8的所有组合。 思路 最直观的思路是两层for循环暴力遍历,if判断两个数之和是否为M,如果不是,则继续枚举,显然时间复杂度很高。 根据题目的序列是递增的特点,可以使用两个下标——下标i指向序列的第一个元素,下标j指向序...
two pointers 充分序列递增性质 使用2个下标i、j对序列进行扫描(同向扫描、反向扫描),以较低的复杂度(一般是O(n)的复杂度)解决问题。
A summation operator and a list with two pointers are used to check the interferences between components in a minimum number of steps. Then, a ternary bees algorithm is proposed to identify new disassembly sequences and directions. The algorithm combines the merits of a greedy search and meta-...
The default algorithm used to compare arrays is naive and can generate a lot of operations. For example, if a single element locatedin the middleof the array is deleted, all items to its right will be shifted one position to the left, generating onereplaceoperation per item. ...

A 1D version of the proposed ARIS algorithm is presented first, laying the foundation for a multidimensional formulation later. We use an advection-reaction equation to advect the phase volume fraction and to sharpen the interface. ARIS is based on the advection-diffusion-reaction equation, which ...
