You need to create a function f(n, l) that takes two inputs:

1. n: A value that can be one of the following types:

   • A string
   • An integer (positive or negative)
   • A boolean (True or False)

2. l: An integer representing the desired minimum length of the output.

The function must return a string of length l by padding n with zeroes (0) in a specific way based on the input type. If the length of n is greater than or equal to l, it should return n unchanged.

Behavior:

1. If n is:

   • A string: Pad it with trailing zeroes (0) from the right until its length equals l.
   • A positive or negative number: Convert it to a string and pad with leading zeroes (0) from the left (after the sign for negatives) until its length equals l.
   • A boolean: Convert it to 1 for True and 0 for False, then pad with leading zeroes (0) from the left until its length equals l.

2. If the length of n is greater than or equal to l, return n as-is without truncation.

   
   

Constraints:

• l will always be greater than or equal to the desired length of n when padding is applied.
• The solution must be a code golf style, with a maximum length of 25 characters.

Examples:

f('-122121', 5)  # "-122121"
f(122121, 5)     # "122121"
f(-122121, 5)    # "-122121"
f(12, 5)         # "00012"
f('ab', 5)       # "ab000"
f(True, 5)       # "00001"
f(False, 5)      # "00000"
