[Jprogramming] Is there a way to distinguish input 1 from 01 ?

[Piet de Jong]

I was hoping for a verb u that would tell me generally how many zeroes are at the front of eg  0001001 so that I could distinguish it from 1001.

Thinking about things I want u such that (u y) returns both the y and the number of zeroes fronting y.
