Numericals of a String
You are given an input string.
For each symbol in the string if it’s the first character occurrence, replace it with a ‘1’, else replace it with the amount of times you’ve already seen it…
But will your code be performant enough?
Examples
input = “Hello, World!”
result = “1112111121311”
input = “aaaaaaaaaaaa”
result = “123456789101112”
There might be some non-ascii characters in the string.
