Answer:
<em>def without_end(strg):</em>
<em> if len(strg)>2:</em>
<em> return strg[1:-1]</em>
<em> else:</em>
<em> return strg</em>
Explanation:
Given above is a function in Python for solving this problem, we can try different output for this program by calling this function in a print statement
print(without_end ("hello")) output ell
print(without_end ("java")) output av
print(without_end ("coding")) output odin
Complete Question:
Fill in the missing step in the following deadlock situation. Two users from the local board of education are each running a program (P1 and P2), and both programs will eventually need two DVD drives to copy files from one disc to another. Only two DVD-R drives are available and they’re allocated on an “as requested” basis. Soon the following sequence transpires:
1. P1 requests drive 1 and gets it.
2. ____
3. P1 requests drive 2 but is blocked.
4. P2 requests drive 1 but is blocked.
a.P1 requests drive 2.
b.P2 requests drive 2 and gets it.
c.P2 requests drive 1 but is blocked.
d.P1 releases drive 1.
Answer:
Soon the following sequence transpires:
P2 requests drive 2 and gets it.
Explanation:
A deadlock is a condition where two computer programs allocate the same resource essentially prevent access by each other and both programs stop working.
When every process or thread is awaiting for a resource to be released which is managed by another process a number of processes or themes are blocked.
Here is an example of a deadlock scenario. All connections are blocked; everybody hopes to see an incident that never takes place.
