First

function colorPatternTimes(colors: string[]): number {
  const res = [colors[0]]
  return colors.forEach(color => res[res.length - 1] !== color && res.push(color)), res.length - 1 + colors.length * 2
}

console.log(colorPatternTimes(["Blue"])) //=> 2
console.log(colorPatternTimes(["Red", "Yellow", "Green", "Blue"])) //=> 11
console.log(colorPatternTimes(["Blue", "Blue", "Blue", "Red", "Red", "Red"])) //=> 13

Second

function plant(seed: string, water: number, fert: number, temp: number): string {
  const stem = '-'.repeat(water)
  const flower = seed.repeat(fert)
  return temp < 20 || temp > 30 ? stem.repeat(water) + seed : (stem + flower).repeat(water)
}

console.log(plant("@", 3, 3, 25)) //=> ---@@@---@@@---@@@
console.log(plant("#", 1, 5, 30)) //=> -#####
console.log(plant("§", 3, 3, 15)) //=> ---------§
console.log(plant("&", 5, 1, 20)) //=> -----&-----&-----&-----&-----&
