*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!

@sayan chandran

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)!!!
