Python

I want to get a list of monotonically increasing subsets when given a string of numbers "by using recursion"

When splitting a string into substrings, the integer represented by the first substring must exceed 'number'(second argument)

def increasing_number(string, number=0):

for example

print(increasing_number('123456'))

output:

[[1, 2, 3, 4, 5, 6], [1, 2, 3, 4, 56], [1, 2, 3, 456], [1, 2, 34, 56], [1, 2, 3456], [1, 23, 456], [1, 23456], [12, 34, 56], [12, 3456], [123, 456], [123456]]
