Last update on June 06 2025 12:51:01 (UTC/GMT +8 hours)

Write a Ruby program to create a new string from a given string using the first three characters or whatever is there if the string is less than length 3. Return n copies of the string.

Ruby Code:

def multiple_string(str, n)
    str.length < 3 ? str*n : str[0..2]*n
end

print multiple_string('abcdefg', 1),"\n"
print multiple_string('abcdefg', 2),"\n"
print multiple_string('abcdef', 1),"\n"
print multiple_string('abcdef', 2),"\n"
print multiple_string('abc', 1),"\n"
print multiple_string('ab', 2),"\n"

Output:

abc
abcabc
abc
abcabc
abc
abab
