reversed() method performs in-place reversal , so no extra space is required. Below is the Python code given: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 # import array module import array # integer array arr = array.array('i',[10, 20, 30, 40, 50, 60]) print("Original array ...
Hint: Could you do it in-place with O(1) extra space? Related problem:Reverse Words in a String II 解题思路: 要想满足O(1) space and in O(n) time, 只有一种方法:reversal. Assuming we are given {1,2,3,4,5,6} and order 2. The basic idea is: 1. Divide the array two parts:...

The only way to sort a primitive array in descending order is first to sort it in ascending order and thenreverse the array in placeas shown here.Since in place reversal is an efficient algorithm and doesn't require extra memory, you can use it sort and reverse large array as well. You...

Many developers simply love using functional constructs when they can, so it's no surprise that reversing an array is commonly done via functional constructs as well. This approach allows you to also pipe in another transformation alongside reversal, such as adding or changing the elements as well...
