Given an array of strings patterns
and a string word
, return the number of strings in patterns
that exist as a substring in word
.
A substring is a contiguous sequence of characters within a string.
Example 1:
Input: patterns = [ "a ", "abc ", "bc ", "d "], word = "abc " Output: 3 Explanation: - "a " appears as a substring in "abc ". - "abc " appears as a substring in "abc ". - "bc " appears as a substring in "abc ". - "d " does not appear as a substring in "abc ". 3 of the strings in patterns appear as a substring in word.
Example 2:
Input: patterns = [ "a ", "b ", "c "], word = "aaaaabbbbb " Output: 2 Explanation: - "a " appears as a substring in "aaaaabbbbb ". - "b " appears as a substring in "aaaaabbbbb ". - "c " does not appear as a substring in "aaaaabbbbb ". 2 of the strings in patterns appear as a substring in word.
Example 3:
Input: patterns = [ "a ", "a ", "a "], word = "ab " Output: 3 Explanation: Each of the patterns appears as a substring in word "ab ".
Constraints:
1 <= patterns.length <= 100
1 <= patterns[i].length <= 100
1 <= word.length <= 100
patterns[i]
and word
consist of lowercase English letters.program main

This script uses the `len` function to get the length of the `word` and `patterns` arrays, and the `size` function to get the number of elements in the `patterns` array. It then uses a nested loop to iterate through the `patterns` array and the `word` string, checking if each pattern is a substring of the `word` string. If it is, the count is incremented and the loop is exited. The final count is output to stdout.
Note that this script assumes that the `patterns` array is a 1D array of strings, and that the `word` string is a single string. If the input is not in this format, the script will need to be modified accordingly.
Also note that this script uses the `implicit none` statement, which is a good practice to use in all Fortran programs. It prevents the use of undeclared variables and helps to catch errors at compile time.
Also note that this script uses the `parameter` statement to define the maximum length of the `word` and `patterns` arrays. This is a good practice to use in all Fortran programs, as it helps to prevent buffer overflows and other security issues.
Also note that this script uses the `character(len=string_length)` type to define the `word` and `patterns` arrays. This is a good practice to use in all Fortran programs, as it helps to prevent buffer overflows and other security issues.
Also note that this script uses the `read` statement to read the input from stdin, and the `write` statement to output the result to stdout. This is a good practice to use in all Fortran programs, as it helps to make the program more flexible and reusable.
Also note that this script uses the `exit` statement to exit the inner loop when a match is found. This is a good practice to use in all Fortran programs, as it helps to improve the performance of the program by avoiding unnecessary iterations.

return 0

current_vowels = word[0]
for i in range(1, len(word)):

The algorithm starts by checking if the input word is long enough to have a beautiful substring; otherwise, it returns 0 as no such substring can exist. Then, it initializes variables to track the maximum length of the beautiful substring, the current length of a candidate substring, and a string of vowels seen so far in the order they've appeared (`currentVowels`).
In the loop that goes through the input word, the algorithm checks if the current character is greater than or equal to the previous vowel and if it is not already in the currentVowels
. If true, it adds the current character to currentVowels
. If the current character is equal to the previous vowel, it does nothing. If the current character doesn't satisfy either of the previous conditions, it resets currentVowels
to the current character and sets the currentLength
to 0.
Finally, for each iteration, it increments currentLength
and checks if the currentVowels
matches the beautiful substring condition ("aeiou"). If true, it updates the maxLength if the currentLength
is greater than the current maxLength.
Once the loop is done, the algorithm returns the maxLength found.
