You must be aware that this is a trial and error process.
The very first digit is easy to pick. It's 5 because it doesn't exceed 33 and it's the highest possible number amongst others. Pick a 6 first and you get 36 when being squared; not what we want. Second digit is trickier. I suggest that you start at '5', which means your very first number is 5.5. If it's smaller than 33, then you continue on by increasing the second digit. Same process is used for other digits, but you need to make sure that all digits selected will not exceed 33 when you square it.
Hope it helps :)
