|

! Take the number 192 and multiply it by each of 1, 2, and 3:

! 192 × 1 = 192
|

! 192 × 2 = 384
|

! 192 × 3 = 576
|

|

! By concatenating each product we get the 1 to 9 pandigital, 192384576. We
|

! will call 192384576 the concatenated product of 192 and (1,2,3)
|
||||
|
||||
! The same can be achieved by starting with 9 and multiplying by 1, 2, 3, 4,
|
||||
! and 5, giving the pandigital, 918273645, which is the concatenated product of

|

! [a+b+c] by one for each triple's sum AND its multiples under 1000 (to account

! DESCRIPTION
|
||||
! -----------
|
||||
|
||||
! It turns out that 12 cm is the smallest length of wire can be bent to form a
|
||||
! right angle triangle in exactly one way, but there are many more examples.
|
||||
|
||||
! 12 cm: (3,4,5)
|
||||
! 24 cm: (6,8,10)
|
||||
! 30 cm: (5,12,13)
|
||||
! 36 cm: (9,12,15)
|
||||
! 40 cm: (8,15,17)
|
||||
! 48 cm: (12,16,20)
|
||||
|
||||
! In contrast, some lengths of wire, like 20 cm, cannot be bent to form a right
|
||||
! angle triangle, and other lengths allow more than one solution to be found;
|
||||
! for example, using 120 cm it is possible to form exactly three different
|
||||
! right angle triangles.
|
||||
|
||||
! 120 cm: (30,40,50), (20,48,52), (24,45,51)
|
||||
|
||||
! Given that L is the length of the wire, for how many values of L ≤ 1,000,000
|
||||
! can exactly one right angle triangle be formed?
|
||||
|
||||
|
||||
! SOLUTION
|
||||
! --------
|
||||
|
||||
! Algorithm adapted from http://mathworld.wolfram.com/PythagoreanTriple.html
|
||||
! Identical implementation as problem #39
|
||||
|
||||
! Basically, this makes an array of 1000000 zeros, recursively creates
|
||||
! primitive triples using the three transforms and then increments the array at
|
||||
! index [a+b+c] by one for each triple's sum AND its multiples under 1000000
|
||||
! (to account for non-primitive triples). The answer is just the total number
|
||||
! of indexes that are equal to one.
