Answer:
B. until another thread issues a notify on the semaphore.
Explanation:
A semaphore is a variable that is shared between threads and is not negative. It also acts as a calling mechanism that uses two atomic operations wait and signal for synchronization of processes.
A thread that is waiting for a process can be signaled by another thread.
A semaphore puts a thread to sleep until another thread issues a notify on the semaphore.
The wait operation will get a semaphore or otherwise wait if the busy S semaphore is available.
The signal operation will release a semaphore or wake a process if there is a thread waiting for S.
Answer: It arranges text in a list alphabetically from A to Z.
Explanation: It's always easier and more systematic to arrange alphabetically. With numbers there is the possibility of infinity but not with alphabet which have a defined range.
The code below is used to determine a recursive, bool-valued function, isPalindrome, that accepts an integer-valued array, and the number of elements and returns whether the array is a palindrome.
Explanation:
- The code shows 'array palindrome' is an array which, when its elements are reversed, remains the same.
bool isPalindrome(arr[((n-1) - n) +1], n)
{
if (n == 0 || n == 1)
{
return true;
}
else if (arr[n-1] == isPalindrome(arr[], n-1)
{
return true;
}
else {
return false;
}
}
Answer:
for(String s:words)
if(s.endsWith("ing"))
System.out.println(s);
Explanation:
Create an enhanced for loop that iterates through the words array
Check if an element in words ends with "ing" using endsWith() method (Since it is said that strings are lowercase letters, we do not need to check it)
If you find one that ends with "ing", print the element
