# [Leet Code] Build Array from Permutation

Leet Code: https://leetcode.com/problems/build-array-from-permutation/

Problem:

Given a **zero-based permutation** `nums`

(**0-indexed**), build an array `ans`

of the **same length** where `ans[i] = nums[nums[i]]`

for each `0 <= i < nums.length`

and return it.

A **zero-based permutation** `nums`

is an array of **distinct** integers from `0`

to `nums.length - 1`

(**inclusive**).

**Example 1:**

**Input:** nums = [0,2,1,5,3,4]

**Output:** [0,1,2,4,5,3]

Explanation: The array ans is built as follows:

ans =…
