Challenge 1:
- On python console
===================
i = 0
sum = 1
i = 2
s = 10
while True:
  sum *= i
  i = i+1
  t = 0
  for j in range(len(str(sum))):
    t += int(str(sum)[j])
  if t > 8000 :
    print t
  if t == 8001:
    print "FOUND: " + str(i-1) + "
    break

===================
Challenge 2:
- On chrome console
===================

var jq = document.createElement('script');
jq.src = "https://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js";
document.getElementsByTagName('head')[0].appendChild(jq);

var sum = 0;

Challenge 3:
- On python console
===================

while i > 0:
  sum += 900.0/i
  i = i-1

tsum = 0
while tsum/sum<0.5:
  i = i+1
  tsum += 900.0/i

print "ANSWER: " + str(i)
