Mainīt dotās virknes dzimumu
Mainiet virknes dzimumu, ti, pārslēdziet visus dzimuma vārdus ievades virknē.
Piemēri:
Input: she is my sister Output: he is my brother. There are two gender-specific words in this sentence:she and sister. After toggling gender specific words to their respective counterparts - he and brother : Gender specific words of the string are now changed.
Algoritms:
- Uzturiet hash-karti, kas visus sievietes vārdus apzīmē ar vīriešu vārdiem un visus vīriešu vārdus sievietēm.
- Tad katram virknes vārdam mēs pārbaudām, vai tas ir dzimuma vārds vai nē. Ja tas ir, tad mēs apmaināmies ar šo vārdu ar tā kolēģa vārdu. Citādi mēs nemainām šo vārdu.
- Visi vārdi tiek salikti jaunā virknē, kas beigās ir iespiesta un ir mūsu nepieciešamā virkne.

Laika sarežģītība: O (n^2), kur n ir virknes garums, jo virknes “+”/ “papildinājums” var aizņemt līdz O (n) laiku un pieņemt, ka meklēšana vārdnīcā prasa O (1) sliktāku gadījumu.
Papildu telpa: Papildus vārdnīcai, kas kartē visus vārdus līdz savam kolēģim, mēs deklarējam O (n) vietu jaunajai virknei, kur n ir ievades virknes garums.
Uzlabošanas joma:
- Mēs varam pievienot vairāk vārdu un to kolēģus vārdnīcā, lai palielinātu programmas precizitāti. Piemēram, mēs varam pievienot - aktieri aktrisi dieva dievietei mūsu vārdnīcai.
- Var importēt arī visu sieviešu un vīriešu vārdu teksta failu.
- Programmu var modificēt, lai kļūtu par gadījumu nejutīgu.
