How does the author most develop Spunk's character over the course of the story?

is 65292

1.Three pairs of digit sum up to 11

So.5+6,4+7,3+8,2+9

So, password must consist of 2 to 9 numbers to make a pair 11.

No 0 or 1.

2.Also it has only 5 digit. So any two number must be same.

3. as per other condition.. 1st and last digit can't be same and also 3 middle digits can't have 2 same number.

4. Last and first digit can be

6___2

9___3

No other options suit for three times the last digit.

5. For middle numbers..

_529_ is the only option and 2 is a repeator that can make third pair as sum of 11.

_63(11)_ error and also 6 is a repeator but it can't make sum as 11.. Anyway error case.

_74(12)_error also no repeators

So.. Now from step 4 and 5..

65292 is the password.
