Первый задача

function reverseTree(len: number) {
  const stars = Array<number>(len).fill(0).map<number>((el, idx) => idx+1).reverse()
  for (let row: number = 1; row < len * 2; row++) {
    let offset: number = Math.abs((len - row)%len);
    process.stdout.write(`${Array(offset).fill(" ").join('')}${Array(stars[offset]).fill("*").join(" ")}\n`)
