Function

expandString(inputStr: String) → String

Examples

Example 1

inputStr = "(ab)(3)"return = "ababab"

In the given string S = "(ab)(3)", P_1=ab, N_1=3. So, to expand string S, pattern P_1 will be concatenated N_1 times as "ab" + "ab" + "ab" to give the final output. So, the output is "ababab".

Example 2

inputStr = "(ab)(3)(cd)(2)"return = "abababcdcd"

In the given string S = "(ab)(3)(cd)(2)", P_1=ab, N_1=3 and P_2=cd, N_2=2.
