Nominal data is qualitative data; non-numeric data; observations are organized into categories without any recognition of order.
<h3>What is
qualitative data?</h3>
Qualitative data is information that cannot be counted, measured or easily expressed using numbers.
It is collected from text, audio and images and shared through data visualization tools, such as word clouds, concept maps, graph databases, timelines and infographics.
Qualitative data is the descriptive and conceptual findings collected through questionnaires, interviews, or observation.
Analyzing qualitative data allows us to explore ideas and further explain quantitative results.
For example, it could be notes taken during a focus group on the quality of the food at Cafe Mac, or responses from an open-ended questionnaire.

Explanation:
The history object in javascript corresponds to browsing history.
It has the following methods for navigating through the history list:
back(): Go back in the history list
forward(): Go forward in the history list
go() : Navigate to the currently pointed url in the history list. It takes a parameter which can either be a numeric index or a string which is matched with the history list content.
replace() is not a method in the history object.
Answer:
int sumid=0; /* Shared var that contains the sum of the process ids currently accessing the file */
int waiting=0; /* Number of process waiting on the semaphore OkToAccess */
semaphore mutex=1; /* Our good old Semaphore variable ;) */
semaphore OKToAccess=0; /* The synchronization semaphore */
get_access(int id)
{
sem_wait(mutex);
while(sumid+id > n) {
waiting++;
sem_signal(mutex);
sem_wait(OKToAccess);
sem_wait(mutex);
}
sumid += id;
sem_signal(mutex);
}
release_access(int id)
{
int i;
sem_wait(mutex);
sumid -= id;
for (i=0; i < waiting;++i) {
sem_signal(OKToAccess);
}
waiting = 0;
sem_signal(mutex);
}
main()
{
get_access(id);
do_stuff();
release_access(id);
}
Some points to note about the solution:
release_access wakes up all waiting processes. It is NOT ok to wake up the first waiting process in this problem --- that process may have too large a value of id. Also, more than one process may be eligible to go in (if those processes have small ids) when one process releases access.
woken up processes try to see if they can get in. If not, they go back to sleep.
waiting is set to 0 in release_access after the for loop. That avoids unnecessary signals from subsequent release_accesses. Those signals would not make the solution wrong, just less efficient as processes will be woken up unnecessarily.
