Complete main() to read dates from input, one date per line. Each date's format must be as follows: March 1, 1990. Any date not following that format is incorrect and should be ignored. Use the substr() function to parse the string and extract the date. The input ends with -1 on al line alone. Output each correct date as: 3-1-1990. Ex: If the input is: March 1, 1990 April 2 1995 7/15/20 December 13, 2003 -1 then the output is: 3-1-1990 12-13-2003 Use the provided GetMonthAsInt() function to convert a month string to an integer. If the month string is valid, an integer in the range 1 to 12 inclusive is returned, otherwise 0 is returned. Ex: GetMonthAs Int("February") returns 2 and GetMonthAs Int("7/15/20") returns 0.

Create a function that takes a string and returns the number of alphanumeric characters that occur more than once. Examples duplicateCount("abcde") duplicateCount("aabbcde") → 2 duplicateCount("Indivisibilities") - duplicateCount("Aa") 0 // Case sensitive N

Please help! There is a bug in my program that causes it to jump to the notfound function before checking the entire substring The program should determine whether the second string is a substring of the first. If it is, then the program should print out the first index in which the second string appears in the first. As an example, if the first string is “Hello World” and the second string is “lo”, then the program should print out 3, i.e. the starting index of “lo” in “Hello World.” If the second string is not contained in the first string, then the program should print out -1. Here is the code:  .datastr1: .space 51 #space for str1 (max50 characters including null terminator)str2: .space 51 #space for str2 (max50 characters incl null terminator)msg1: .asciiz "Please enter the first string: " #prompt user to enter str1msg2: .asciiz "Please enter the second string: " #prompt user to enter str2newline: .asciiz "\n" .text.globl mainmain:    # Print sttr1    li $v0, 4    la $a0, msg1…

Create a function that will test if a string is a valid PIN or not via a regular expression. A valid PIN has: Exactly 4 or 6 characters. Only numeric characters (0-9). • No whitespace. Examples validate("121317") → true validate("1234") → true validate("45135") → false validate("89abc1") → false validate("900876") → true validate(" 4983") false
