    TS solution O(n): 

    function permutationEquation(p: number[]): number[] {
    // Write your code here
    
    let map: {[key: number]: number} = {}
    
    for(let i = 0; i < p.length; i++) {
        map[p[i]] = i + 1
    }
    
    let result: number[] = []
    
    for(let i = 1; i <= p.length; i++) {
        let pypy: number = map[map[i]]
        result.push(pypy)
    }
    
    return result
}
