You are given a 0-indexed integer array nums having length n, an integer indexDifference, and an integer valueDifference.Your task is to find two indices i and j, both in the range [0, n - 1], that satisfy the following conditions:abs(i - j) >= indexDifference, andabs(nums[i] - nums[j]) >= valueDifferenceReturn an integer array answer, where answer = [i, j] if there are two such indices, and answer = [-1, -1] otherwise. If there are multiple choices for the two indices, return any of them.Note: i and j may be equal. Example 1:Input: nums = [5,1,4,1], indexDifference = 2, valueDifference = 4Output: [0,3]Explanation: In this example, i = 0 and j = 3 can be selected.abs(0 - 3) >= 2 and abs(nums[0] - nums[3]) >= 4.Hence, a valid answer is [0,3].[3,0] is also a valid answer.Example 2:Input: nums = [2,1], indexDifference = 0, valueDifference = 0Output: [0,0]Explanation: In this example, i = 0 and j = 0 can be selected.abs(0 - 0) >= 0 and abs(nums[0] - nums[0]) >= 0.Hence, a valid answer is [0,0].Other valid answers are [0,1], [1,0], and [1,1].Example 3:Input: nums = [1,2,3], indexDifference = 2, valueDifference = 4Output: [-1,-1]Explanation: In this example, it can be shown that it is impossible to find two indices that satisfy both conditions.Hence, [-1,-1] is returned. Constraints:1 <= n == nums.length <= 1050 <= nums[i] <= 1090 <= indexDifference <= 1050 <= valueDifference <= 109

You are given two 0-indexed integer arrays nums1 and nums2 of sizes n and m, respectively.Consider calculating the following values:The number of indices i such that 0 <= i < n and nums1[i] occurs at least once in nums2.The number of indices i such that 0 <= i < m and nums2[i] occurs at least once in nums1.Return an integer array answer of size 2 containing the two values in the above order.

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).

Given an array Arr of N positive integers. Your task is to find the elements whose value is equal to that of its index value ( Consider 1-based indexing ).

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

Problem Statement You are given a function, static int ElementsAndIndices(int[] arr){} 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. Your code is judged by an automated system, do not write any additional welcome/greeting messages. "Save and Test" only checks for basic test cases, more rigorous cases will be used to judge your code while scoring. Additional score will be given for writing optimized code both in terms of memory and execution time.
