How to remove leading zeros in Groovy?

In Groovy, you can use the replaceAll() method to remove leading zeros from a string. For example, if you have a string str that contains leading zeros, you can remove them using the following code:

1

str = str.replaceAll(/^0+/, '')

This will replace any sequence of zeros at the beginning of the string with an empty string, effectively removing the leading zeros.

In Groovy, you can remove leading zeros from a number or string by converting it to a number or integer format first and then back to a string. Here is an example:

1
2
3
4
5
6

def input = "000123"

// Convert the string to a number and then back to a string
def output = input.toInteger().toString()

println(output)  // Output: 123

Note: This approach assumes that the input will always be a valid number or an integer as a string.
