You are climbing a stair case. It takes n steps to reach to the top.
Each time you can either climb 1 or 2 steps. In how many distinct ways can you climb to the top?
func climbStairs(_ n: Int) -> Int {
if n < 4 { return n }
var arr = Array(repeating: 1, count: n+1)
arr[2] = 2; arr[3] = 3
for i in (4...n) {
arr[i] = arr[i-1] + arr[i-2]
}
return arr[n]
}
