function getRandomLowercaseLetter() {
    const randomCharCode = Math.floor(Math.random() * 26) + 97; // 97 is ASCII/Unicode code for 'a'
     
    return String.fromCharCode(randomCharCode);
}
 
function GetRandomLowercaseString(n: number) {
    let s: string = "";
 
    for(let i: number = 0; i < n; i++ ) {
        s += getRandomLowercaseLetter()
    }
  
    return s;
