WebNumber of occurrence. Given a sorted array Arr of size N and a number X, you need to find the number of occurrences of X in Arr. Input: N = 7, X = 2 Arr [] = {1, 1, 2, 2, 2, 2, 3} Output: 4 Explanation: 2 occurs 4 times in the given array. Input: N = 7, X = 4 Arr [] = {1, 1, 2, 2, 2, 2, 3} Output: 0 Explanation: 4 is not present in the given array. WebNov 23, 2024 · A simple solution is consider every subarray and count 1’s in every subarray. Finally return size of largest subarray with all 1’s. An efficient solution is traverse array from left to right. If we see a 1, we increment count and compare it with maximum so far. If we see a 0, we reset count as 0. Implementation:

WebThe frequency of an element is the number of times it occurs in an array. You are given an integer array nums and an integer k. In one operation, you can choose an index of nums and increment the element at that index by 1. Return the maximum possible frequency … WebJan 10, 2024 · A sliding window approach generally helps us reduce the time complexity for brute force approaches. Given an array of integers of size ‘n’. Our aim is to calculate the maximum sum possible for ...
WebInput: nums = [1,2,2,3,1,4,2] Output: 6 Explanation: The degree is 3 because the element 2 is repeated 3 times. So [2,2,3,1,4,2] is the shortest subarray, therefore returning 6. Constraints: nums.length will be between 1 and 50,000. nums [i] will be an integer between 0 and 49,999.

Examples: Input: arr [] = {1, 1, 1, 2, 3, 3, 5, 5, 8, 8, 8, 9, 9, 10} Output: Frequency of 1 is: 3 Frequency of 2 is: 1 Frequency of 3 is: 2 Frequency of 5 is: 2 Frequency of 8 is: 3 Frequency of 9 is: 2 Frequency of 10 is: 1
WebJan 4, 2024 · Approach: Make a visited array of type boolean. Use the first loop to point to an element of the array. Initialize the variable count to 1. Make that index true in the visited array. Run second loop, if we find the element then mark the visited index true and increase the count. If the visited index is already true then skip the other steps. Code: WebJun 9, 2024 · Approach: Initialize count = 0 and traverse the array from arr [0] to arr [n – 2]. If the current element is equal to the next element in the array then increment the count. Print the count in the end. Below is the implementation of the above approach: C++ Java Python3 C# PHP Javascript #include using namespace std;

Webfrequency of at least one of the chosen numbers is different. The test cases are generated such that the number of unique combinations that sum up to target is less than 150 combinations for the given input. Example 1: Input: candidates = [2,3,6,7], target = 7 Output: [ [2,2,3], [7]] Explanation: 2 and 3 are candidates, and 2 + 2 + 3 = 7. home page icon edgeWebFor each i, check if nums[i] is in the map. If it is, then add that count to the overall count. Then, increment the frequency of nums[i]. Runtime: 98 ms, faster than 10.67% of Java online submissions for Count Nice Pairs in an Array.
