Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response. It is important to use strong passwords to make the Internet more secure. At the same time, it is very important not to reuse the same password. No matter how strong your password is, if the plaintext is leaked in one place, it will be very easy to break. Of course, if all applications hash passwords and use SALT properly, such damage will not occur even if leaked, but there are still applications that store passwords in clear text. Well, the contest is about to begin. I have to register a team account ... problem A string representing the password is given. Check if the character string meets all of the following conditions, and if it meets all of the following conditions, output "VALID", and if there is an item that does not meet even one, output "INVALID". * String length is 6 or more * Contains one or more numbers * Contains one or more uppercase letters * Contains one or more lowercase letters input A string representing the password is given on one line. output Print "VALID" if the password string meets all the conditions in question, and "INVALID" if there are conditions that do not. Constraint * The password string must be between 1 and 20 characters. * Password string contains only uppercase letters, lowercase letters, and numbers Input / output example Input 1 password Output 1 INVALID It is a password that is widely used all over the world. Input 2 AizuCamp2013 Output 2 VALID Great password. Input 3 1234 Output 3 INVALID Widely used as a PIN. Input 4 NaBiO3 Output 4 VALID It is barely 6 characters or more. Example Input password Output INVALID Submitted Solution: ``` num = list("0123456789") large = list("ABCDEFGHIJKLMNOPQRSTUVWXYZ") small = list("abcdefghijklmnopqrstuvwxyz") S = input() if len(S) < 6: print("INVALID") exit() flag_n, flag_l, flag_s = False, False, False for s in S: if s in num: flag_n = True elif s in large: flag_l = True elif s in small: flag_s = True if flag_n and flag_l and flag_s: print("VALID") else: print("INVALID") ```

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response. You want to perform the combo on your opponent in one popular fighting game. The combo is the string s consisting of n lowercase Latin letters. To perform the combo, you have to press all buttons in the order they appear in s. I.e. if s="abca" then you have to press 'a', then 'b', 'c' and 'a' again. You know that you will spend m wrong tries to perform the combo and during the i-th try you will make a mistake right after p_i-th button (1 ≤ p_i < n) (i.e. you will press first p_i buttons right and start performing the combo from the beginning). It is guaranteed that during the m+1-th try you press all buttons right and finally perform the combo. I.e. if s="abca", m=2 and p = [1, 3] then the sequence of pressed buttons will be 'a' (here you're making a mistake and start performing the combo from the beginning), 'a', 'b', 'c', (here you're making a mistake and start performing the combo from the beginning), 'a' (note that at this point you will not perform the combo because of the mistake), 'b', 'c', 'a'. Your task is to calculate for each button (letter) the number of times you'll press it. You have to answer t independent test cases. Input The first line of the input contains one integer t (1 ≤ t ≤ 10^4) — the number of test cases. Then t test cases follow. The first line of each test case contains two integers n and m (2 ≤ n ≤ 2 ⋅ 10^5, 1 ≤ m ≤ 2 ⋅ 10^5) — the length of s and the number of tries correspondingly. The second line of each test case contains the string s consisting of n lowercase Latin letters. The third line of each test case contains m integers p_1, p_2, ..., p_m (1 ≤ p_i < n) — the number of characters pressed right during the i-th try. It is guaranteed that the sum of n and the sum of m both does not exceed 2 ⋅ 10^5 (∑ n ≤ 2 ⋅ 10^5, ∑ m ≤ 2 ⋅ 10^5). It is guaranteed that the answer for each letter does not exceed 2 ⋅ 10^9. Output For each test case, print the answer — 26 integers: the number of times you press the button 'a', the number of times you press the button 'b', ..., the number of times you press the button 'z'.

Wrong tries are "a", "abc" and the final try is "abca". The number of times you press 'a' is 4, 'b' is 2 and 'c' is 2. In the second test case, there are five wrong tries: "co", "codeforc", "cod", "co", "codeforce" and the final try is "codeforces". The number of times you press 'c' is 9, 'd' is 4, 'e' is 5, 'f' is 3, 'o' is 9, 'r' is 3 and 's' is 1.
