How does this function return the first dupe from an array?

I have a task (or more like a challenge) found on Code-Signal (a site where do you can do some programming-related tasks. This special task was asked by google in an interview:

By specifying your variable with an additional $ (variables variable) PHP creates a "hidden/fake array". While running each index gets filled with a "0":

Asked 2018-Nov-25 at 12:44

I would like to extract a very specific portion of a 2D array in Python using the zip() method (and avoid messy for loop logic). I'd like to use zip to achieve something like this:

JavaScript coding interview first repeating character in array not working for null

Asked 2018-Jul-13 at 07:05

THE ISSUE

I'm not sure what I'm doing wrong here. I'm doing a coding challenge on CodeFights using vanilla JavaScript to find and return the first repeating element in an array. My code works for 2 test arrays (a and c) but not for the case where there are no repeating elements.

You want to reset counts each time firstDuplicate is called. Otherwise each call will share the same object.

You are also referencing a in the for loop but should be referencing the arr function parameter.

QUESTION

Reducing the execution time in following program

Asked 2018-Feb-28 at 06:27

I need to optimize my answer for the following question without exceeding time limit (0.5s). This isn't a homework or a competition or my interview question. I'm currently learning programming by my self for fun and I found this online.

Given an array a that contains only numbers in the range from 1 to a.length, find the first duplicate number for which the second occurrence has the minimal index. In other words, if there are more than 1 duplicated numbers, return the number for which the second occurrence has a smaller index than the second occurrence of the other number does. If there are no such elements, return -1.

This is my answer:

First (naive) optimization: start the inner loop at i+1.

Second (also naive, since it uses quite a lot of memory) optimization: Allocate an array of length a.length, initialize to -1. Then, iterate once through your data and as soon as a number is found, store its index. If an index has been found already, you can detect that by checking against -1, and you have your duplicate.

QUESTION

Break out of JavaScript ES6 function not working with return

Asked 2018-Jan-29 at 11:42

THE ISSUE

This feels like it should be simple, but I'm just not getting it for some reason. I decided to take on an apparently common programming interview question to test my skillset:

"Given an array a that contains only numbers in the range from 1 to a.length, find the first duplicate number for which the second occurrence has the minimal index. In other words, if there are more than 1 duplicated numbers, return the number for which the second occurrence has a smaller index than the second occurrence of the other number does."

(source: https://codefights.com/interview-practice/task/pMvymcahZ8dY4g75q)

I believe I have the correct code, but I can't get the loop to stop running. Given the example array, the function should return "3", since that is the first number that repeats (not the first number seen). However, no matter what I try, it either returns 2 or an error.

You are returnig value in foreach function. This function is called for evry element in array and it's return value is ignored.

instead of .forEach() use for loop and return from it.
