#3578
palind
Ana a descoperit că are o adevărată pasiune pentru palindromuri. Un şir de numere este palindrom dacă se citeşte la fel de la stânga la dreapta şi de la dreapta la stânga (primul număr este egal cu ultimul, al doilea cu penultimul etc). Ea are un şir cu N
numere naturale şi vrea ca orice subsecvenţă de lungime impară a şirului să fie palindrom. Pentru a-şi îndeplini dorinţa ea poate efectua asupra şirului mai multe operaţii. O operaţie constă în alegerea unui element din şir şi incrementarea sau decrementarea lui cu o unitate. Bineînţeles, Ana doreşte să utilizeze un număr minim de operaţii pentru ca şirul obţinut să respecte proprietatea amintită mai sus (orice subsecvenţă de lungime impară să fie palindrom).
