You are given an integer arraynums, an integer arrayqueries, and an integerx. For eachqueries[i], you need to find the index of thequeries[i]thoccurrence ofxin thenumsarray. If there are fewer thanqueries[i]occurrences ofx, the answer should be -1 for that query. Return an integer ar...
To check if any element is present in the array, we can find the index of that element and check ifindex >= 0, then the element exists, else it doesn’t. The lastIndexOf method This method returns the index of the last occurrence of matched element in the array. This method searches...
how I find a index of element in a array? Answers (2) 0 Vulpes NA96k2.6m10y Try this: using System; class Program { static void Main() { string[] planets = {"mercury", "venus", "earth", "mars", "saturn", "jupiter", "uranus", "neptune", "pluto"}; ...
One more question. Suppose I want to get the second occurrence when it exists. So for the second element of A which is 2 the positions it shows in B are 3, 6 and 8. Suppose I want the code to return 6. How would I modify it?
Given an array of integersnumssorted in ascending order, find the starting and ending position of a giventargetvalue. Your algorithm's runtime complexity must be in the order ofO(logn). If the target is not found in the array, return[-1, -1]. ...
Find First and Last Position of Element in Sorted Array - LeetCode 注意点 nums可能为空 时间复杂度为O(logn) 解法 解法一:最普通的二分搜索,先找到一个target,然后向两边拓展。 class Solution { public: int binarySearch(vector<int>& nums, int target) { int left = 0,right = nums.size()-1;...
To find the index of an element in an int array in Java, you can use the indexOf() method of the Arrays class. The indexOf() method returns the index of the first occurrence of the specified element in the array, or -1 if the element is not found. Here is an example of how ...
find occurrence of number in array c++ - find most occurring element in an array of integers c++ - separate even & odd numbers in array c++ - find sum of even & odd numbers of array c++ - find product of even & odd numbers of array c++ - search an element in array c++ - so...
Suppose, we have a sorted array of literals like this − const arr = [2, 2, 3, 3, 3, 5, 5, 6, 7, 8, 9]; We are required to write a JavaScript function that takes in one such array and returns the first number that appears only once in the array. If there is no such ...
