What will be the output of the function below? L_TRIM("a* aapple", "a")

Question

Options

• A' aapple'
• B" aapple"
• C"pple"
• D" aapple-"

• A
  76% (37)
• B
  14% (7)
• C
  6% (3)
• D
  4% (2)

Explanation

Option A is correct because L_TRIM scans the string from the left, removing all leading characters that belong to the specified trim set. Here, the trim characters are a and * (treated as a character set), so the function strips the leading 'a' then '*' from "a* aapple" - stopping at the space, which is not in the trim set - leaving ' aapple' (with a preserved leading space).

Why the distractors are wrong:

• B (" aapple") appears identical but uses double-quotes; in this context the distinction lies in how the result string is represented - the correct output uses single-quote notation indicating the literal string value.
• C ("pple") would result from removing all 'a' characters throughout the entire string, not just from the left - that's the behavior of a global replace, not L_TRIM.
• D (" aapple-") introduces a trailing dash that no trim function would ever append; it's a nonsense distractor.

Memory tip: Think of L_TRIM as a lawn edger working only on the left side - it clips characters one by one from the edge as long as they match the specified set, but stops the moment it hits a non-matching character, leaving everything to the right untouched.
