swap

问题 I have an activity which will byteswap the MDN of a device however I need to implement this in a service however I cannot seem to do so. Every time I attempt to add the code to my service I get different errors depending on the method I use and I was told by another developer that I'll need to implement an activity - but this is not an option (it needs to run in the background) so I need to find a method of byteswapping the MDN within either my existing service or another service (or an

问题 For an assignment I need to make a sorting algorithm for n amount of vector arrays. The assignment specifically tells me to not swap the value of what the pointers are pointing to, but the address that is stored in those pointers. The result will then be printed using those pointers. My problem is that I can't seem to accomplish the swapping of the addresses that the pointers contain. I have searched SO for related questions but they almost all change the values of where the pointers are

问题 I'm attempting to pull the byteswapped MDN value from SharedPreferences but it continues to return the value of zero - when it should return the byteswapped MDN instead. I'm saving it using the following format: editor.putString(new String("data"), Integer.toString(0)); and getting it using the following format: String info = String.format("USI%sCN%s,WN%s", tag + status + tag + settings.getString("data", Integer.toString(0)) + tag + DToDevice + tag, mobileStr, totalStr + settings.getString(

问题 I'm trying to compare bubble sort between C++ and MASM. I've got the C++ working without issue. With MASM, however, I need another counter in loopSwap, but I don't know how to go about it. I know that if I push a register, it would have to be before the comparison but if the comparison jump is met, I wouldn't be able to pop the same register. Any help is appreciated! C++ Code: #include <iostream> #include <cmath> #include <ctime> using namespace std; int deepBlueDecend(int* num, int size);

问题 I have a class which has a union as one of its members. I also am a big fan of the copy/swap idiom. It occurred to me that there doesn't appear to be any correct (in the sense of the standard) to swap unions! Here's the best that I could come up with: char tmp[sizeof(U)]; memcpy(tmp, &u1, sizeof(U)); memcpy(&u1, &u2, sizeof(U)); memcpy(&u2, tmp, sizeof(U)); Since unions (at least in c++03) require that all members be POD, I don't see why this wouldn't work. But it just doesn't feel right. Is

问题 I want to reduce the kswapd timeout to increase the performance by use of fast devices like Flash, SSD as swapping devices. 回答1: You can change the behavior of kswapd through 2 ways Through Proc File System From IBM Developerworks, /proc/sys/vm/kswapd Maximum number of pages the kernel tries to free at one time. If you want to increase bandwidth to/from swap, you will need to increase this number. Minimum number of times the kernel tries to free a page on each swap. The number of pages the

问题 This is my table structure , Here i need to swap items .Which means, you can see type 3 always comes paired( type 3 items are always paired ). I just named paired items for understanding first 1 in pair is master and second one is sub. So master of the pair should not come 5,10 and 15 positions if it comes that place i need to swap the next item into that place(neaxt item will be sub it should not considered as next item) for example pid 10 (comes in 10 position) i need to swap it like this

问题 is there a way to swap character places in a string? For example if I have "03/02" I need to get "02/03" . Any help is appreciated! 回答1: Sure: #include <string> #include <algorithm> std::string s = "03/02"; std::swap(s[1], s[4]); 回答2: std::swap(str[1], str[4]); 回答3: There is. :) std::swap(str[i], str[j]) 回答4: Wait, do you really want such a specific answer? You don't care about if the string is 2/3 instead of 02/03? #include <string.h> #include <iostream> bool ReverseString(const char *input)

问题 Can we swap two numbers in Java using pass by reference or call by reference? Recently when I came across swapping two numbers in Java I wrote class Swap{ int a,b; void getNos(){ System.out.println("input nos"); a = scan.nextInt(); b = scan.nextInt(); // where scan is object of scanner class } void swap(){ int temp; temp = this.a; this.a = thisb; this.b = this.a; } } In the main method I call the above mentioned methods and take two integers a , b and then using the second method I swap the

问题 Here's my HTML: <div class="large"> <img src="/images/photos/Interior.jpg" alt="The interior" style="[...]" /> <div class="caption">The interior</div> </div> <div class="small"> <img src="/images/photos/Bedroom.jpg" alt="Bedroom" style="[A different ...]" /> <div class="caption">A bedroom</div> </div> Upon clicking a div.small , I'd like both the images and captions to swap container divs. The catch is I can't just swap the src, as there are a bunch of inline styles set which need to be
