则对于每轮洗牌的过程,使得temp[i] = a[order[i]], 一轮结束后,再将数组temp[] 赋给 a[], 使得a[] = temp[](vector可以直接互相赋值) 如果不使用vector,也可以使用一个循环(伪代码) for (i = 1 to 54) a[i] = temp[i] 来进行赋值 AC代码: 1#include <cstdio>2#include <vector>3#includ...
By applying chosen plaintext combined with chosen ciphertext attack, we demonstrate that a hacker can determine the permutation vector and the whole random code sequence used respectively in permutation and diffusion procedure, which can be exploited to reveal the plain image. Then we proposed an ...

aFor now, nothing certain. 暂时,确定没什么。[translate] aTo address these technical problems, the current study focused on the function of the bacteriophage PhiX174 lysis gene E. Mutations were introduced by gene shuffling, and after screening and recombination with the pBV220 vector, novel mutan...
Thirty-one HVR1 cDNA fragments were digested by DNase I into a pool of random fragments and reassembled by repeated cycles of annealing in the presence of DNA polymerase to their original size. The shuffled HVR1 was then inserted into the gene III phagemid vector pCANTAB-5E and displayed on ...
