First and foremost, avoid declaring a callback within the useEffect. What you need to do is use the useCallBack hook to declare your fetchData callBack

Your code should atleast look like...

1. For objects, the test to_entries|length == 0 can be abbreviated to length==0.

2. If I understand the goal correctly, you could just use .., perhaps along the following lines:

getline takes in the following parameters :

input - the stream to get data from

str - the string to put the data into

delim - the delimiter character

In your call for getline, the third parameter (delim) is supposed to be a character, while you are passing ":" as a string by using double quotes. Pass ':' using single quotes instead of double quotes, it should resolve the error.

This is a sample of one line of the OP's XML file
109555912.69

The OP wants to use the IMPORTXML function to report the ID and Name as well as the Job Cost from the XML data. Presently, the OP's formula is:
=importxml("link","//job-base-cost")

There are two options:
1 - One long column
=importxml("link","//@id | //@name | //job-base-cost")

Note //@id and //@name in the xpath query: // indicate nodes in the document (at any level, not just the root level) and @ indicate attributes. The pipe | operator indicates AND. So the plain english query is to display the id, name and job-base-cost.

2 - Three columns (table format)
={IMPORTXML("link","//@name"),IMPORTXML("link","//job-base-cost"),IMPORTXML("link","//@id")}

This creates a series that will display the fields in each of three columns.

Note: there is an arrayformula that uses a single importXML function described in How do I return multiple columns of data using ImportXML in Google Spreadsheets?. Readers may want to look at whether that option can be implemented.

My thanks to @Tanaike for his comment which spurred me to look at how xpath works.

Your findMedian function assumes that the array is already sorted. But the array in the test case that fails isn't.

math.max can only be applied to 2 arguments - you have 4. If you have four numbers what you can do is:

In short: the code provided is well-formed. It compiles correctly, though there is one mistake in the usage of pow() from that leads to incorrect calculation results (different from those that you might expect). The problem most probably arises when your code meets the test system.

Proof of correctness:

How would I begin to resolve this issue?

First, you need to understand the error message:

Error: Cannot Convert ‘Person*’ To ‘double*’ For Argument ‘1’ to ‘Double stdDev(double[], int)’

This means that there is a function with the signature double stdDev(Person*, int). However, there is no code that calls such a function. There only is an invocation of stdDev(double*, int) in the line double a = stdDev(people, ARRAY_SIZE);. That means that the erroneous invocation comes from elsewhere, but the function is not defined in your code. This means that there is additional code that you can't see, most probably provided by the test system.

Another possibility is that you have a copy of the code with a modification that is escaping your attention. The modification is that instead of
