Given an arrayA, we can perform apancake flip: We choose some positive integerk <= A.length, then reverse the order of the first k elements ofA. We want to perform zero or more pancake flips (doing them one after another in succession) to sort the arrayA. Return the k-values corresp...

Algorithm: Algorithms are basically methods or recipes for solving various problems. To write a program to solve some problems, we first need to know a suitable algorithm. 算法导论:非形式的说,算法就是任何良定义的计算过程,该过程取某个值或者值的集合作为输入并产生某个值或者值的集合作为输出。这样算...
Spawning multiple threads to solve a problem, some problems are easily solved in parallel. Race conditions Threads fight over a shared resource (e.g. thread 1 modifying an ArrayList that thread 2 is trying to read at the same time). Locks A thread can "claim" a resource as its own and...
