# Palindrome Number?

This week I am going to explain my solution the the palindrome number problem. A palindrome is a number that read the same forwards and it does backwards, for example 121 is a palindrome number. In this problem we are given a number and we are tasked with writing a function that returns true for palindrome numbers and false for numbers that are not palindromes. So.. lets get into the solution..

# onlyDigits()

This week I decided to tackle the tech interview question “only digits”. In this problem you are tasked with discovering if a string contains only digits, or only numbers.

# missingNumber()

This weeks coding challange is to find the missing number in a string from 1 to 100. I came to a very quick and simple solution to this one. If we know there is only one number missing in the array all we have to do is make sure the…

# singleInteger()

I have heard about this interview question many times, so this week I decided to take it on. Here is a description of the problem at hand…

Given an array of integers, every element appears twice except for one. Find that single one.

This seems like a very simple problem, but in reality javascript doesn’t have a built in uniq method so it gets pretty complicated.

# twoNumbers()

Two numbers is a fun problem where you are tasked to create a function that takes 2 arguments; an array of numbers and a target. Within the array of numbers there are 2 numbers of which their sum will equal the target. We are then asked to return the indexes…

# Anagram

Running a google search for the word anagram you will see that an anagram is..

`a word, phrase, or name formed by rearranging the letters of another, such as cinema, formed from iceman`

For this blog entry I am going to do a walk through of how to create a…

# Roman Numeral to Integer

Continuing my algorithm practice I ran into a pretty fun and challenging problem. The task is to make a function that takes a roman numeral and returns the value of the numeral as an integer. For example “XL” = 40, “V” = 5, “IV” = 4, and so on.

The…

# 10 + 3= 103??

So in basic math 10 + 10 = 20; well in javascript sometimes this is not the case. There are many times when working with JS that 10 + 10 will equal 1010. What gives? Since “strings” are a very common data type used on the internet a lot of…

# “FizzBuzz”

As you know I have been brushing up on possible interview questions. One that I came across that seems to be extremely common is a question called “FizzBuzz” In this challange you are given numbers and are asked to crate at function that returns “Fizz” if the number is divisible…

# checkIfInteger()

As you know if you have been reading my recent posts, I have been practicing writing algorithms for my next tech interviews. In this installment I am going to walk you trough creating a function that checks if the input is an integer in javascript. An integer is a whole…
