Shuffle a set of numbers without duplicates. Example: // Init an array with set 1, 2, and 3. int[] nums = {1,2,3}; Solution solution = new Solution(nums); // Shuffle the array [1,2,3] and return its result. Any permutation of [1,2,3] must equally lik…

384. Shuffle an Array c++ random函数:https://www.jb51.net/article/124108.htm rand()不需要参数,它会返回一个从0到最大随机数的任意整数,最大随机数的大小通常是固定的一个大整数. 这样,如果你要产生0~10的10个整数,可以表达为: int N = rand() % 11; 这样,N的值就是一个0~10的随机数,如果要产生1~10,则是这样: 总结来说,可以表示为: a + rand() % n 其中的a是起始值,n是整…
