How do you sort an array in reverse order?

Array elements can be sorted in descending order by passing in the array and Collections. reverseOrder() as parameters to Arrays. sort().

How do you reverse a list in descending order python?

If you want to see the elements in descending order, you can use the sort method with the list reverse parameter. A default value of “False” is set up for the list reverse parameter, which means that by default, elements will be sorted in ascending order.

How do I reverse an array in NumPy?

How do you sort an array in descending order using array sort?

Algorithm

1. Start.
2. Declare an array.
3. Initialize the array.
4. Use the Arrays. sort() to sort the elements in ascending order.
5. Then, use Collections. reverseOrder () to reverse the order.
6. The updated array now will be in descending order.
7. Print the updated array.
8. Stop.

1. # Get list length.
2. L = len(numbers)
3. # i goes from 0 to the middle.
4. for i in range(int(L/2)):
5. # Swap each number with the number in.
6. # the mirror position for example first.

8. n = numbers[i]

How do you reverse an array in python without function?

How do I reverse an array?

Solution Steps

1. Place the two pointers (let start and end ) at the start and end of the array.
2. Swap arr[start] and arr[end]
3. Increment start and decrement end with 1.
4. If start reached to the value length/2 or start ≥ end , then terminate otherwise repeat from step 2.
