Is there a way I can make this code that counts the number of duplicate values in an array work for strings?

How to get ASCII value of string in C# I want to get the ASCII value of characters in a string in C#.

I have an old 4GB SD card, and have just bought a new 16GB SD card. I would like to copy everything from my old 4GB SD card onto the new 16GB SD card. I was afraid that the usual copy-and-paste trick would miss out something, so I wanted to clone the old 4GB SD card onto the 16GB SD card. I used the dd command in a shell, following instructions in .  This worked with one small caveat. The new SD card now appeared to be 4GB. I later found out this is because the primary partition on the 16GB SD card has now shrunk to 4GB. I have solved this problem, and I think I understand it. However, my question now is, how do I clone my old 4GB SD card onto my new 16GB SD card without making the primary partition on the 16GB SD card shrink to 4GB? How to make files protected? Polygamma reflection formula How is The Wall bypassed? In H. P. Lovecraft's The Case of Charles Dexter Ward, Dr. Willett      Enters Joseph Curwen's dungeon and resurrects a dead person identified as No. 118 by reciting the incantation of the Ascending Node over his salts.   Dr. Willett is told by      The resurrected Joseph Curwen, impersonating Charles Dexter Ward, who he secretly murdered,   that   " 'twas Number 118, and I conceive you would have shook had you looked it up in my list in t'other room."  No. 118 himself gives Dr. Willett a note asking the doctor to      kill Joseph Curwen.   It soon becomes clear that No. 118 is opposed to the nefarious dealings that have been transpiring and desirous of being an ally of Dr. Willett.  Who is No. 118?  Earlier in the story,      The grave of Ezra Weeden, a primary instigator in Joseph Curwen's initial downfall and the romantic rival of Curwen, is robbed. There doesn't seem to be any other mention of Weeden in the 20th century occurrences, so without a further connection the passage seems superfluous.   The shared goals of these two people seem to indicate that No. 118 may, in fact, have been that person, but the      Note given by No. 118 to Dr. Willett in eighth century Latin seems to indicate someone much older than Ezra Weeden.   It also occurred to me that No. 118 could be      The recently murdered Charles Dexter Ward himself. Ward's reference to killing Dr. Allen (who is actually an alias of Curwen) and dissolving his body with acid and No. 118's mention of doing the same to Curwen seem to support the idea, but that still doesn't explain the archaic note. Ward is described as writing in a somewhat modern style, at least as opposed to Curwen. It also doesn't explain why Curwen would want to murder Ward if he was going to resurrect him later anyway. Given a collection of sets $\mathcal{C}$ and $E$ an element in the $\sigma$-algebra generated by $\mathcal{C}$, how do I show that $\exists$ a countable subcollection $\mathcal{C_0} \subset \mathcal{C}$ such that $E$ is an element of the $\sigma$-algebra, $\mathcal{A}$ generated by $\mathcal{C_0}$?    The hint says to let $H$ be the union of all $\sigma$-algebras generated by countable subsets of $\mathcal{C}$....although I don't know why. I need to monitor the network activities of a process and the bandwidth of the connection. So I decided to use nethog and netperf combine with grep and awk to write the values to a file.   nethog command: nethogs -t  eth0 | grep firefox | awk '{ print $3 }' (I want to take the upload/download speed). The 1st problem is that command doesn't print anything.  More detail: command: nethogs -t  eth0 | grep firefox output:  usr/lib/firefox/firefox-bi�)/4956/1000  0.338867    0.239063 /usr/lib/firefox/firefox-bi�)/4956/1000 0.543555    0.274219 /usr/lib/firefox/firefox-bi�)/4956/1000 0.794531    0.489844 /usr/lib/firefox/firefox-bi�)/4956/1000 0.794531    0.489844 /usr/lib/firefox/firefox-bi�)/4956/1000 0.749023    0.589844 /usr/lib/firefox/firefox-bi�)/4956/1000 1.30098 3.47617 /usr/lib/firefox/firefox-bi�)/4956/1000 1.90449 8.0127 /usr/lib/firefox/firefox-bi�)/4956/1000 5.31641 25.0033 /usr/lib/firefox/firefox-bi�)/4956/1000 8.60762 42.0176   I want the two values at the bottom right. But as you can see the output ain't consistent (the space), add | awk '{print $3}' most of the time return nothing. And I can't fix this.  netperf command: netperf -H 192.168.1.10 and the output is:  Recv   Send    Send                           Socket Socket  Message  Elapsed               Size   Size    Size     Time     Throughput   bytes  bytes   bytes    secs.    10^6bits/sec    524288 524288 262144    10.00    **718.62**   I want to print the value on the bottom right but have no idea how to. That's the 2nd problem => solved by  fedorqui!  Can you guys help me out? Any ideas will be appreciated! I have a dual monitor set-up. When I'm on YouTube, and I click the fullscreen icon, the fullscreen automatically goes to the second monitor. How do I get it to go fullscreen on my main monitor? Run VirtualBox in background, without a window? I was wondering if it's possible to run an Ubuntu virtual machine using VirtualBox in background, I mean, without any window open.  The idea is to connect via SSH to the Linux host, that would be running in background.  Has anyone ever done something like this? Is it possible? How can I sort arrays and data in PHP? Where $F$,$K$ are two fields. What does the element in the composite field $FK$ look like? All the elements are generated by the elements of $F$ and $K$? (combination of the elements of $F$ and $K$) I think $FK$ is pretty close to the free product of $F$ and $K$; is $FK \subsetneq F*K$? Thank you! What is the JavaScript version of sleep()? Community isn't on ~15 sites! I use babelbib and I have a source with two authors. Contrarily to when using the plain bib style, as soon as I switch to babplain, the author names are formatted like this:  [1] Müller, Jan und Eva Schulze: Name of the book, 2015.   While I would like both author names to be formatted the same way, that is one of these:  [1] Müller, Jan und Schulze, Eva: Name of the book, 2015. [1] Jan Müller und Eva Schulze: Name of the book, 2015.   sources:  % test.tex \usepackage[ngerman]{babel} \usepackage[fixlanguage]{babelbib} \selectbiblanguage{ngerman} \bibliographystyle{babplain} \bibliography{test}  % test.bib @manual{foo,     author = "Müller, Jan and Schulze, Eva",     title = "Name of the book",     year = "2015", }   I can fix it by specifying and {Schulze, Eva}, but that way all is treated as the last name, that cannot be the solution, can it? Google sheets split multi-line cell into new rows (+ duplicate surrounding row entries) Is there a fast way (without looping over all edges/faces/verts) using ops.mesh or bmesh to get the lists of indices associated with mesh islands as shown below? These islands are part of one mesh but are disjoint from each other.    I know how to select the boundaries by running the operator Select boundary Loop or calling bpy.ops.mesh.region_to_loop() but can't find any API calls to return the vert/edge/face indices associated with the individual islands.
