StringSearch | High-perfor­mance pattern matching algo­rithms in Java | Architecture library

I see a couple of issues. First, the code doesn't have a return statement for every logical branch. I mean that, for every condition in an if, then, else statement, the code should have a return statement or some sort of control-flow statement (e.g. a recursive call or a continue) that will eventually lead to a return statement.

The second issue is the while loop. Supposedly, right should be greater than left from the beginning of the function (unless the length of smallString is 0) because right is the length of smallerString minus 1. The while condition is left > right, so nothing inside of the while will be executed unless smallString has a negative length (which it doesn't).

By the way, if you want to check the entire bigString, you will need to iterate over bigString, not smallString. If you are only checking smallString.length characters, you won't be checking the entire bigString. Figuring out how to write this function is a good exercise, so I will leave the writing of it to you and refrain from providing an implementation myself. Keep up the good work!

Suggestions

1. Variable naming

Why line2 followed by line1? Better to name in successive order i.e. line1, line2.

Or even better relate variable name to its purpose and use Python naming convention thus:

The first thing you need to make sure that your invoice is not on hold - if it is on hold then the entity returned by the Get will be empty. That could be a problem.

Also, can you please try using ReleaseInvoice() instead of Release() in the invoke?

InvokeResult invokeResult = client.Invoke(invoice, new ReleaseInvoice());

That has worked for me in the past.

Something like below

Apart from the issues pointed out in the comments there is some things you should improve:

• char * string = (char *) malloc(WordSize * sizeof(char)); is the same as char * string = malloc(WordSize), but for a 20 word string we will need char * string = malloc(WordSize + 1)

• This part of the code:

First of all, you should check if the access token is valid, you can send a request using postman.

If the token is valid, I think it should be the problem of your jsonInputString. The following code works fine.

Here's one approach -

1. Let's consider a counter which holds a counter for all the readLine() method invocations - representing the "row" in the .txt file. So, increment the counter after every readLine call in the while loop.
2. Next, split the line on " " (space) to get an array of each word in the line. Then, you could iterate over this array and match the word to the search string. The position of array index at the time the match was found will represent the "column".
