Sort 0s, 1s and 2s

Difficulty: MediumAccuracy: 50.58%Submissions: 851K+Points: 4Average Time: 10m

Given an array arr[] containing only 0s, 1s, and 2s. Sort the array in ascending order.
Note: You need to solve this problem without utilizing the built-in sort function.

Examples:

Input: arr[] = [0, 1, 2, 0, 1, 2]
Output: [0, 0, 1, 1, 2, 2]
Explanation: 0s, 1s and 2s are segregated into ascending order.
Input: arr[] = [0, 1, 1, 0, 1, 2, 1, 2, 0, 0, 0, 1]
Output: [0, 0, 0, 0, 0, 1, 1, 1, 1, 1, 2, 2]
Explanation: 0s, 1s and 2s are segregated into ascending order.
MY CODE:
class Solution:
    def sort012(self, arr):
        arr.sort()
        return(arr)

  CA 09 - Move All Negative Elements to end Move all negative elements to end Difficulty:  Easy Accuracy:  56.24% Submissions:  174K+ Points:  2 Given an unsorted array  arr[ ]  having both negative and positive integers. The task is to place all negative elements at the end of the array without changing the order of positive elements and negative elements. Note :  Don't return any array, just in-place on the array. Examples: Input : arr[] = [1, -1, 3, 2, -7, -5, 11, 6 ] Output : [1, 3, 2, 11, 6, -1, -7, -5] Explanation: By doing operations we separated the integers without changing the order. Input : arr[] = [-5, 7, -3, -4, 9, 10, -1, 11] Output : [7, 9, 10, 11, -5, -3, -4, -1] MY CODE: class Solution: def segregateElements(self, arr): a = [] b = [] for i in arr: if i >= 0: a.append(i) else: b.append(i) temp = a + b fo...

  CA 06 - Find the Maximum and Minimum Element in the Array Min and Max in Array Input: arr[] = [1, 4, 3, 5, 8, 6] Output: [1, 8] Explanation: minimum and maximum elements of array are 1 and 8. Input: arr[] = [12, 3, 15, 7, 9] Output: [3, 15] Explanation: minimum and maximum element of array are 3 and 15. MY CODE: The min and max are the functions which shows the maximum and minimum element class Solution: class Solution: def getMinMax(self, arr): a = arr[0] # min b = arr[0] # max for c in range(1, len(arr)): d = arr[c] if d < a: a = d if d > b: b = d return [a, b]
