Input - firstname lastname
Output - lastname, fistname

Input - 1 integer(n)
Output - print all numbers from 0 to n
Output - print all even numbers from 0 to n
Output - print all odd numbers from 0 to n
Output - determine whether the integer is even, odd or zero.

Input - 1 integer(n), 1 string("odd" or "even")
Output - if the string entered is "even", print all even numbers from 0 to n
Output - if the string entered is "odd", print all odd numbers from 0 to n

Input - 1 integer (ex:12345)
Output - digits seperated by a space (ex:1 2 3 4 5)

Input - n integers
Output - Min, Max, Sum and Product of those n integers
Output - Print the largest 2 numbers (input: 1,2,3,4,5 output: 4,5)

Input - n integers
Output - Number of integers entered
Output - Number of even integers
Output - Number of odd integers
Output - Number of integers that are zero

Input - none
Output
number	square	cube
0	0	0
1	1	1
2	4	8
3	9	27
4	16	64
5	25	125
6	36	206
7	49	343
8	64	512
9	81	729
10	100	1000

Input - none
Output - use for loops and only System.out.print("* "), System.out.print(" ") and System.out.println("")

Input - none
Output - 2,4,8,16,32,64.... etc (create infinite loop, you will have to hit CTRL+c, to stop program)

Input - integer (ex: n=5)
Output - 2,4,8,16,32  (loop upto the nth power of 2)

Input - 3 positive integers (a,b,c)
Output - Determine if those values can be the sides of a right triangle (a2=b2+c2)
(You should not assume that the first integer is the hypotenuse. If b2=a2+c2 or c2=a2+b2 holds true, the program should evaluate this as a possible triangle)

Input - integer (n=500)
Output - Print out all the Pythagorean Triples, hypotenuse being no larger than the input n
ex: (3,4,5) (4,3,5) (5,3,4) (5,4,3) (5,12,13) (6,8,10)....... (300,400,500)
Output - modify the program to not print out duplicate entries such as (3,4,5), (4,3,5), (5,3,4), (5,4,3)
Output - modify the program to not print out "similar" triangles. (3,4,5) is similar to (6,8,10). (all sides multiplied by a coeficcient)

Input - 1 integer: n>0
Output - compute the factorial: n! = n(n-1)(n-2)...(2)(1)

Input - none
Output - compute the value of PI: PI=4-4/3+4/5-4/7+4/9-4/11+...  (3.14159...)
Output - compute the constant e: e=1+1/1!+1/2!+1/3!+1/4!+...    (2.71828...)

Input - 1 integer (x)
Output - compute the value of e^x using the formula e=1+x/1!+x^2/2!+x^3/3!+x^4/4!+...
