Zilola ingliz tili to'garagiga qatnaydi. Ular to'garakda shu oy ichida ko'proq ″Reading ″ mashq qilishmoqda. Shuning uchun ustozi har kuni o'quvchilarga har xil matn berib tushunib tarjima qilib kelishni topshirmoqda. Zilola matnni tarjima qilayotganida notanish so'z uchrab qolsa tagiga chizib qo'yardi. Va ushbu kunlik lug'atni alifbo tartibi bo'yicha saralab lug'at daftariga yozib qo'yardi. Agar ushbu notanish so'zlar ichida oldin ham lug'at daftariga yozganlari bo'lsa uni yozmas edi. Uning bir oy davomida har kungi yozgan so'zlarini (\(i\)- test uchun faqat shu kundagi) va shu so'zlardan keyin endi daftarida jami nechta so'z borligini chop eting.

Kiruvchi ma'lumotlar:

Sizga faqat tagiga chizilgan so'zlar ko'rinadigan qilib matn beriladi.
ushbu so'zlar soni \(1500\) dan oshmaydi.
Barchasi kichik harflarda beriladi.

\(i- \text {kundagi matn}\ i-\text{testda beriladi}\).

Chiquvchi ma'lumotlar:

Masala javobini chop eting.
Eslatma :
1. Takrorlangan so'zlardan faqat bitta olinadi
2. \(i-\) kundagi biror so'z oldingi kunlardagi biror lug'atda mavjud bo'lsa, bu so'z yozilmaydi.
