With these it helps For some reason, I can't get this to work! Can anyone tell me where I've gone wrong? This is supposed to reverse the words in a give string (i.e from "this is a test" to "test a is this")
code :
words[currentWord] = words[currentWord] + input[i];
ret = ret + words[i];

this one helps. Hello & it's nice to be with you all. I was successful in reversing arrays using the built-in functions .split('').reverse().join('') presented in this site, but I need to keep digits in order, not reversed. Is there anything to do or to add to let it exclude the digits from being reversed, or to re-reverse the digits only after reversing the full array? Here's the array flipping function,
code :
"hello 123.45".split(/([^\d\.])/).reverse().join('')

it should still fix some issue So in yours reverseMessage function You are trying to swap variable for that you are doing
array[i] = array[j]; array[j] = array[i];
code :
 function reverseMessage(string) {
     var array = string.split(" ");
     //loop through array and replace first index with last index, second
     //index with second to last index, third index with third to last index, etc
     for (var i = 0,j=(array.length)-1; i < array.length/2; i++) {
             temp=array[i]
             array[i] = array[j];
             array[j]=array[i]
             array[j] = temp; j--;}
       console.log(array.join(" "));
 };  reverseMessage("find you will pain only go you recordings security the into if");

This might help you What you could do is to create an array of all the words in the string, reverse the array and then start replacing each word in the string with the words in the reversed array.
Here is an example:
code :
function process(s){
  let arr = s.replace(/\W+$/, "").split(/\W+/).reverse();
  let index = 0;
  return s.replace(/\w+/g, function(){
    return arr[index++].split("").reverse().join("");
  });
}

console.log(process("hello  howis.going"));

wish help you to fix your issue Regarding part 1, I think this should work, and I would recommend using a regex and not string.split for finding words.You could also use nltk.word_tokenize if your sentences have complex words and punctuation. They are both slower than string.split, but if you need them, they're useful.
Here's a couple decent posts highlighting the differences (wordpunct-tokenize is basically a word regex in disguise):
code :
import re

num_matches = 3

def get_words(input):
    return re.compile('\w+').findall(input)

my_string = 'she said he replied'
my_list = ['This is a cool sentence', 'This is another sentence','she said hello he replied goodbye', 'she replied', 'Some more sentences in here', 'et cetera et cetera...']

my_string_word_set = set(get_words(my_string))
my_list_words_set = [set(get_words(x)) for x in my_list]

result = [len(my_string_word_set.intersection(x)) >= num_matches for x in my_list_words_set]
print(result)
words = get_words(my_string)
first_and_last = [words[0], words[-1]]
my_list_dicts = []
for sentence in my_list:
    word_dict = {}
    sentence_words = get_words(sentence)
    for i, word in enumerate(sentence_words):
        word_dict[word] = i
    my_list_dicts.append(word_dict)

result2 = []
for word_dict in my_list_dicts:
    if all(k in word_dict for k in first_and_last) and word_dict[first_and_last[0]] < word_dict[first_and_last[1]]:
        result2.append(True)
    else:
        result2.append(False)

print(result2)
