A325)Could you please help me to solve this problem?

Problem:

Write Standard ML function(s) to find the number of vowels and nonvowels in the strings sent as parameter in a list, and returns the strings and their count of vowels and nonvowels in a record list.

Sample Run:

-find([“good”,”luck”,”on”,”your”,”homework”]);

val it =

[{word="good",vowels=2,nonvowels=2},{ word="luck,vowels=1,nonvowels=3},

   { word="on",vowels=1,nonvowels=1},{ word="your",vowels=2,nonvowels=2 },

   { word="homework",vowels=3,nonvowels=5 }] : wrdrec list

Note:

Use the following list in your program to specify the vowels.

val vowels=[#”a”, #”e”, #”i”, #”o”, #”u”];

Use the explode function which changes a string to a char list.

- explode "abc";

   val it = [#"a",#"b",#"c"] : char list

You can write as many functions as needed.

Do not forget to declare your types.

Explanation / Answer

var vowels=[a,e,i,o,u]

var words=[“good”,”luck”,”on”,”your”,”homework”]

var charc=[]

var i=0

while i<words.length
do

var vowel = 0

var nonVowels = 0

charc = [];

var word = words[i];
var j=0

while j<word.length

charc[j] = word.charAt(j);
j=j+1

var k=0

while k< vowels.length
  
do

if(charc[j] == vowels[k]) vowel = vowel + 1 else nonVowels = nonVowels + 1
