Need to find three integers which can equal Pythagoras' Theorem (a^2+ b^2= C^2) and a+b+c=1000
Have tried with some math logics to solve this problem .
a^2+ b^2= C^2
a+b+c=1000
Finally with help of computer solved this problem..
for a in 1..500
for b in 1..500
for c in 1..500
if (a+b+c) == 1000
if (a*a) +(b*b) == (c*c)
p a,b,c
exit
end
end
end
end
end
Results : 200 ,375 ,425

Ruby : How to list all methods of element or object?
A way to list methods of list in ruby
> list=[1,2,3,4,5] # define one list
=> [1, 2, 3, 4, 5]
> list.sort
=> [1, 2, 3, 4, 5]
> list.methods.sort -1.methods # -1 exclude other object methods.
