There were three coding question and you have to solve them in 1.5hr (offline - In the office)

Q.1 The problem presents us with a list of strings called words, and another string s. We are asked to determine if s is an acronym for the words. An acronym in this context is defined as a string that can be formed by taking the first character of each string in words, in their respective order. For instance, given words = ["keep", "it", "simple", "stupid"], the string s = "kiss" would be an acronym of words because taking the first letter of each word in order produces "kiss" but if the s="kis" then its false beacuse both are not equal.

constraints: pretty low around 100

Q.2 Suppose you have n integers from 1 through n. A permutation of those n integers is considered a Divisible Permutation if for every i, where 1 <= i <= n, either of the following is true:
perm[i] is divisible by i.
i is divisible by perm[i].

Given an integer n, find the total number of the valid Divisible Permutations.

Example 1:
Input: n = 2
Output: 2

Explanation:
The first Divisible Permutation is [1,2]:
permutation[1] = 1 is divisible by i = 1
permutation[2] = 2 is divisible by i = 2

The second Divisible Permutation is [2,1]:
permutation[1] = 2 is divisible by i = 1
i = 2 is divisible by permutation[2] = 1

constraints: 1<=n<=15
