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...
This post provides an overview of available methods to find an index of the first occurrence of an element in the array in C++. 1. Naive solution A simple solution is to write our own custom routine for finding the index of the first occurrence of an element. The idea is to perform a...
This post will discuss how to find the index of the first occurrence of an element in a C++ array.1. Using std::findThe C++ standard library offers the std::find function which returns an iterator to the first matching element in the specified range, or an iterator to the end of the ...
Find the element that appears once in sorted array JavaScript - 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 return
This method returns the index of the first occurrence of matched element in the array. If no element matches, then it returns -1. This method is case-sensitive. constshop=['Amazon','Flipkart','Wallmart','Myntra','Flipkart']; ...
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]. ...
