CountMultiX

Now let change our function to compare against an entire string instead of a single character. This function should accept a string and a substring to compare against. The number of occurrences of the second parameter within the first parameter string are returned. What this means is that we are checking the number of occurrences of the shorter string (second parameter) within the longer string (first parameter). One way to accomplish this is using the split function.

• Define the function to accept two parameters. word for the input string and x for the second string we are searching for
• Split the string into substrings based on the second input parameter
• Count the number of instances the substring appeared in the first input string based on the split string
• Return the results

In our function we split the first input string using the second input string. What this does is cut the first string into an array of smallers substrings containing the parts not equal to our second parameter x. In order to get the correct result we need to return one less then the total number of split sections. In this example, "iss" was in the string twice, resulting in 3 sections. So we should return 3 - 1.
