示例：Rearrange('b c (h p1) (w p2) -> b (c p1 p2) h w', p1=2, p2=2)         数据重排（rearrange）通常用于深度学习框架中调整多维数据的维度顺序。这种操作在处理图像数据、执行矩阵乘法或构建如卷积神经网络（CNN）等架构时非常常见。 在给定的表达式中： 'b' 代表批次大小（batch size）。'c' 代表通

Rearrange an array using swap with 0.  You have two arrays src, tgt, containing two permutations of the numbers 0..n-1. You would like to rearrange src so that it equals tgt. The only allowed ope

Given an array of positive and negative integers, re-arrange it  so that you have postives on one end and negatives on the other,  BUT retain the original order of appearance.  For eg. 1, 7,
