A Pythagorean Triplets is a set of three integers a, b, c such that a2+b2=C2. In the given limit L. Find the number of Pythagorean Triplets R that can be formed (such that a<b<c).

Create a class called time that has separate int member data for hours, minutes, and

seconds. One constructor should initialize this data to 0, and another should initialize it

to fixed values. Another member function should display it, in 11:59:59 format. The final

member function should add two objects of type time passed as arguments. A main() program should create two initialized time objects (should they be const?) and one that isn’t initialized. Then it should add the two initialized values together, leaving the result in the third time variable. Finally it should display the value of this third variable. Make appropriate member functions const.

Implement your own version of the priority queue data structure using java with OOPs principles mentioned functionalities: enqueue, Dequeue (highest priority), peek(highest priority), contains, size, center, sort reverse, iterator, traverse/print.

Use of similar data structures already present in the language/framework is not allowed.

Area and Perimeter of square

you are given a side of square as input.Write a program to find the perimeter and area of square.

input

the input is an integer representing the length of the side of the square

output

the first line of the output should contain area of the square, and the second line of the output should contain the perimeter of the square as per the format shown in the sample output.

explanation

given the length of the side is 2 .

as the area of square is side*side and perimeter of the square is 4*side

the output should be

area of the square is : 4

perimeter of the square is : 8

sample input 1

3

sample output 1

area of the square is : 9

perimeter of the square is : 12

sample input 2

4

sample output 2

area of the square is : 16

perimeter of the square is : 16

Elements in the range

You are given three numbers. Check if any of the numbers exist in the range from 10 to 20(including 10 to 20).

input

the first,second and third lines of inputs are the integers.

output

the output should be either True or False

Explanation

Given a = 2,b = 4,c = 16 , 16 is in the range between 10 and 20.

so the output should be True.

sample input 1

2

4

16

sample output 1

True

sample input 2

2

4

6

sample output 2

False

String repetition-4

you are a given string.repeat the same string N times separated by space.

explanation

in the given example the string is messages , N = 3 .

so we have to repeat the string three times.then we get messages messages messages

as output

sample input 1

messages

3

sample output 1

messages messages messages

sample input 2

pop

4

sample output 2

pop pop pop pop

compare last three characters

write a program to check if the last three characters in the given two strings are same.

input

the first and second lines of inputs are the same.

output

the output should be either True or False

Explanation

given strings are apple , pimple. in both strings,the last three characters ple are common.

sample input 1

apple

pimple

sample output 1

True

sample input 2

meals

deal

sample output 2

False
