Which is the best way to shuffle an array?
Advantage: You can random multiple arrays simultaneously without disrupting the mapping. And ‘random_state’ can control the shuffling for reproducible behavior. The other answers are the easiest, however it’s a bit annoying that the random.shuffle method doesn’t actually return anything – it just sorts the given list.
How to shuffle an array using STL in C + +?
Shuffle an Array using STL in C++. Given an array, the task is to shuffle the whole array and print it. STL contains two methods which can be used to get a shuffled array. These are namely shuffle() and random_shuffle(). This method rearranges the elements in the range [first, last) randomly, using g as a uniform random number generator.
How to randomize ( Shuffle ) a JavaScript array?
You can do it easily with map and sort: You can shuffle polymorphic arrays, and the sort is as random as Math.random, which is good enough for most purposes.
How to return a shuffled array in Python?

Where do the odd and even elements appear in a sorted array?
When both the elements are even: In this case, the smaller element must appear in the left of the larger element in the sorted array. When both the elements are odd: The larger element must appear on left of the smaller element. One is odd and the other is even: The element which is odd must appear on the left of the even element.
How to segregate odd and even numbers in an array?
The problem is very similar to our old post Segregate 0s and 1s in an array, and both of these problems are variation of famous Dutch national flag problem. Algorithm: segregateEvenOdd () 1) Initialize two index variables left and right: left = 0, right = size -1 2) Keep incrementing left index until we see an even number.
