A function that compare if there is duplicate numbers in a array

You have two arrays: one with the original numbers, and one with the result, where you collect the duplicate numbers.

You are looping over the original array. that is a good start.

array[i] is the current number of the original array.

How can you find out if it is has already occured before, and is therefore duplicate? that's the next step in your algorithm that you have to figure out.

you probably need another loop, or another array, and probably an if somewhere.

bcrypt compare returning false when password contains numbers
In your beforeValidate function you are passing in 10 as the salt you need to generate your salt, change that function to this beforeValidate: function(user, model, cb) { var salt = bcrypt.genSalt(10); bcrypt.hash(user.password, salt, function(err, hash) { if ( err ) { throw err; } user.password = hash; cb(null, user); }); }

Compare two arrays to get the missing array and new array in java
You can use guava libraries for getting the difference between the sets. What you can do is convert bothe the arrays to Set new HashSet(Arrays.asList(array)); And similalarly for the sencond array as well Then pass the Sets to guava difference method public static Sets.SetView difference(Set set1, Set set2) .If you don't want to use any 3rd party libraries, You can check out this question ques

compare elements positions in first array with another array
Its just a loop. function checkArrays( arrA, arrB ){ for(var i = 0; i < arrA.length; i++) { if(arrA[i] !== arrB [i]) return arrB [i] }; } If you're allowed to use ECMAScript 6 a.find(function(v, i){ return v !== d[i] })

compare Java Double.Max_VALUE with large double numbers returns true
I think the problem is in this line | v new Double(Double.MAX_VALUE).equals(new Double(Double.MAX_VALUE - 99999999999999999999999D)) DOUBLE MAX_VALUE = Double.MAX_VALUE - 99999999999999999999999D AND you're comparing it with new Double(Double.MAX_VALUE - 99999999999999999999999D

Find triplets in an array such that sum of two numbers is also a number in the given array
At first glance, I can't see an algorithm that is less than O(n²). (Unless it is an extra-ordinarily clever one) This problem is very similar to the infamous 3SUM question: Basically, the idea is that given a set of n elements, are there any triples that sum to zero? An algorithm solving 3SUM faster than O(n²) is not known - This is an open problem in computer science... (See here: http://en.
