-#Никола Светославов - task2
-
-## Задачи
-
-1. Напишете програма,която проверява дали въведена от потребителя година е високосна.
-   **Проверете сами кои години се считат за високосни**
-
-2. Напишете програма, която приема един символ от входа и проверява дали:
-
-    * този символ е буква от латинската азбука;
-    * ако да, дали тази буква е гласна или съгласна.
-
-    **Програмата да работи както за малки, така и за главни букви**
-
-3. Напишете програма, която приема две **различни** числа и казва кое е по голямо.
-   **Използвайте тернарен оператор**
-
-4. Напишете програма, която приема от входа три числа - страни на триъгълник.
-   Програмата да проверява дали това е валиден триъгълник.
-
-5. Напишете програма, която намира корените на квадратно уравнение.
-   За целта потребителя да въведе коефицентите на уравнението - *a*, *b*, и *c*
-   при уравнение с вид *a \* x^2 + b \* x + c = 0*.
-
-6. Напишете прост калкулатор, който поддържа операциите +, -, *, / на две реални числа.
-   **Внимавайте с делението на 0**
-
-7. Да се състави програма, чрез която се въвежда 4-цифренo естествено число от интервала [1000.. 9999].
-   От това число се формират 2 нови 2-цифрени числа. Първото число се формира от 1-та и 4-та цифра на въведеното
-   число. Второто число се формира от 2-рa - 3-та цифра на въведеното число.На екрана да се изведе дали
-   1-то ново число e по-малко <, равно = или по-голямо от 2-то число.
-   Използвайте проверка на логическо условие - оператор if.
-   //Задачата е взета от [тук](http://1001zadachi.com/оператор_if_сравняване_числа.html).
-    
-    **Пример: 3332 Изход: less (32<33)
-    **Пример: 1144 Изход: equal (14=14)
-    **Пример: 9875 Изход: greater (95>87)
