DAILY CHALLENGE : Write a sscanf like function.

The function gets a string s and a string p (pattern) and returns an array of variables. The pattern can contain: - %d for integer AND double - %s for string - %c for character - any normal asci-char example 1: p = "%c'am %d" s = "I'am 25" result = sscanf(s,p) = ['I',25] example 2: p = "good %s!" s = "good night!" result = sscanf(s,p) = ["night"] info: - If s doesn't match p -> return an empty array - If you can't return arrays with different types store the values as strings and return a string array!

This took me...about 3 straight hours. And I TOTALLY FORGOT TO ACCOUNT FOR %D ACCEPTING FLOATS. But...it works. It Goddamn works lol. %s only takes alpha chars that can be divided by single spaces into consideration. Spaces, unless %s is being applied are ignored and must correspond to both strings in positioning. All text that doesn't correspond to %d, %s and %c are ignored, and must correspond in positioning, or it fails and returns an empty array. For example; "this is returned 25 ignored #" and "%s %d ignored %c" will pass, however, "this is returned 25 ignored #" and "%s%d ignored %c" will fail, because there is not a space in between %s and %d. EDIT: %d works for float input now. Woot! https://code.sololearn.com/cUu9QopM2ZL5/?ref=app

theres a question i want to ask @ JULIAN @ 1st eg:::: suppose the string is--> hi 2 meet %d so if the pattern is -----> hi %d %s %d the last %d (in p) is not as the pattern its because the string have it... 2nd eg:::: now here is the catch again suppose the string is--> hi 2 meet %s so if the pattern is -----> hi %d %s %s the last %s (in p) is as detecting of a string not because in s its there.. how the compiler will understand 1st example is not a error even the 2nd one is also not..???????? how will the compiler know if the pattern as p have %d/%s/%c as detection or as the input string have it????

EXAMPLE 3: s = "nice 2 meet you!" p = "nice %d %s%c" result = sscanf(s,p) = [2, "meet you", '!'] EXAMPLE 4: s = "ok" p = "%d" res = sscanf(s,p) = [ ] AND PLEASE DO NOT USE ANY BUILT-IN FUNCTION LIKE FORMAT(etc)!!!
