smaller elements to the right of that respective elementGiven an List of integers, you need to return a new list where each element in the new list is the number of smaller elements to the right of that respective element in the original input list.For example:You are given the List of integer values [3, 4, 9, 6, 1] and the resultant list you return is [1, 1, 2, 1, 0].Explanation:There is 1 smaller element to the right of 3There is 1 smaller element to the right of 4There are 2 smaller elements to the right of 9There is 1 smaller element to the right of 6There are no i.e. 0 smaller elements to the right of 1Constraint: Input list can contain positive as well as negative integer values.You Just have to complete the function get_smaller_right(arr) where arr is the list of integer elements passed, and function will return the resultant array as required.Instruction: To execute your custom test cases, please provide input as mentioned in the visible sample test cases.Sample Test CasesTest Case 1:Expected Output:Enter·the·elements·of·the·list·separated·by·spaces:·3 4 9 6 1The·resultant·sub·array·is:·[1,·1,·2,·1,·0]Test Case 2:Expected Output:Enter·the·elements·of·the·list·separated·by·spaces:·1 2 3 4 5The·resultant·sub·array·is:·[0,·0,·0,·0,·0]Test Case 3:Expected Output:Enter·the·elements·of·the·list·separated·by·spaces:·5 4 3 2 1The·resultant·sub·array·is:·[4,·3,·2,·1,·0]
Solution
Here is a Python solution for the problem:
def get_smaller_right(arr):
n = len(arr)
result = [0]*n
for i in range(n):
count = 0
for j in range(i+1, n):
if arr[j] < arr[i]:
count += 1
result[i] = count
return result
This function works by iterating over each element in the input list. For each element, it counts the number of elements to its right that are smaller than it. This count is then stored in the corresponding position in the result list.
For example, if the input list is [3, 4, 9, 6, 1], the function will return [1, 1, 2, 1, 0].
This solution has a time complexity of O(n^2) because for each element in the list, it iterates over all the elements to its right. If the input list is very large, this solution may be slow. However, it is simple and easy to understand.

You are given two integers n and x. You have to construct an array of positive integers nums of size n where for every 0 <= i < n - 1, nums[i + 1] is greater than nums[i], and the result of the bitwise AND operation between all elements of nums is x.Return the minimum possible value of nums[n - 1]. Example 1:Input: n = 3, x = 4Output: 6Explanation:nums can be [4,5,6] and its last element is 6.Example 2:Input: n = 2, x = 7Output: 15Explanation:nums can be [7,15] and its last element is 15. Constraints:1 <= n, x <= 108
You are given an integer array nums sorted in non-decreasing order.Build and return an integer array result with the same length as nums such that result[i] is equal to the summation of absolute differences between nums[i] and all the other elements in the array.In other words, result[i] is equal to sum(|nums[i]-nums[j]|) where 0 <= j < nums.length and j != i (0-indexed). Example 1:Input: nums = [2,3,5]Output: [4,3,5]Explanation: Assuming the arrays are 0-indexed, thenresult[0] = |2-2| + |2-3| + |2-5| = 0 + 1 + 3 = 4,result[1] = |3-2| + |3-3| + |3-5| = 1 + 0 + 2 = 3,result[2] = |5-2| + |5-3| + |5-5| = 3 + 2 + 0 = 5.Example 2:Input: nums = [1,4,6,8,10]Output: [24,15,13,15,21]
Problem Statement You are given a function, int ElementsAndIndices(int arr[], int n); The function takes an integer array 'arr' of size 'n' as its arguments. Implement the function to find and return the number of array elements which are equal to their index value in array i.e. arr[k] = k, 0 <= k < n. Note: Indexing starts from 0. Return -1 if 'arr' is empty or None in case of python Example: Input: 10 1 12 3 5 8 9 7 12 23 Output: 3 Explanation: Index Element 0 10 1 1 2 12 3 3 4 5 5 8 6 9 7 7 8 12 9 23 Elements at index {1, 3, 7} are equal to their index values {1, 3, 7} respectively. Since, these are 3 elements, thus, output is 3. The custom input format for the above case: 10 10 1 12 3 5 8 9 7 12 23 (The first line represents the size of the array, the second line represents the elements of the array) Sample input -3 0 1 3 5 7 Sample Output 1 The custom input format for the above case: 6 -3 0 1 3 5 7 (The first line represents the size of the array, the second line represents the elements of the array) Instructions : This is a template based question, DO NOT write the "main" function.
