# DGM interview with Aida

### Check if a string is a palindrome:

const isPalindrome = (s: string): boolean => 
    for(var i=0;i<s.length/2;i++) {
        if (s[i] !== s[s.length-i-1]) {
            return false;
        }
    }
    return true;
;

const isPalindrome = (s: string): boolean => s.split('').reverse().join('') === s;

#### Test Cases

isPalindrome("aba")
-> true
isPalindrome("abb")
-> false
isPalindrome("abcca")
-> false

### Given an list of numbers, return the greatest number without using sort.

const greatest = (ns: number[]): number => 
    let max_val: number = ns[0];
    for (var i=0;i<ns.length;i++){
        if(ns[i] > max_val) {
            max_val = ns[i];
        }
    }
    return max_val;
;

const greatest = (ns: number[]): number|undefined => ns.slice().sort()[ns.length-1];
const greatest = (ns: number[]): number|undefined => Math.max(...ns); 
const greatest = (ns: number[]): number|undefined => ns.reduce((m,x) => x > m ? x : m, ns[0]);

#### Test Cases

greatest([1,4,3,2,7,4])
-> 7

//Thank you for the time that everyone put into this. I loved the collaboration in the team based on the interview. I'm not sure how fast you are looking to bring a new member on the team but can I start today or tomorrow? :D
