You are given an array A1,A2...AN. You have to tell how many pairs (i, j) exist such that 1 ≤ i < j ≤ N and Ai XOR Aj is odd. Input and Output First line T, the number of testcases. Each testcase: first line N, followed by N...

I'm trying to get an application to XOR two hexadecimal values and output the result as a decimal value. I have searched the Internet for an answer, but every result simply gives a true or false result. The figures I am using as an example are Value 1 = 0F8F...

Given a matrix of size NxN. Rows and Columns are numbered from 0 to N-1. jth column of ith row contains i xor j. In other words, Matrix[i][j] = i ^ j where 0 ? i,j < N. Your task is to find the maximum value occurring in this...

I have matrix A(na*7) and matrix B(nb*7). (ex. A(16*7) and matrix B(110*7)) A and B both have 1's and 0's as context. I want to perform xor operation between each row of A and each row of B and count the number of 1's in the result and store it...

I am attempting to make a JSP that takes text from the text area and depending on whether you select encode or decode, will encode your text or decode the encoded text. The encode part works, but the decode option throws org.apache.jasper.JasperException: java.lang.NumberFormatException: For input string: "". Here is my...

I am writing a program in which the requirements are as follows Has a string variable called Name that is set to your full name, including spaces. Clears the AL register only, NOT the rest of the EAX register. Loops through each character in the Name variable. Combines each character...

I am trying to do a simple xor encryption routine in Swift. I know this is not a particularly secure or great method but I just need it to be simple. I know how the code is implemented in Javascript I'm just having trouble translating it to Swift. Javascript: function...

count "0 xor 1 xor 2 xor......xor N",for instance,i give number three as N , the program should return 0,now i put my code to the online jundge ,the result is time limt exceed,i can hardly find where the error is ,can any one give me some advice,thanks in advance....

I have a dumb question, and I am embarrassed to even ask. Due to my little knowledge in math I couldn't figure out what should I search. I'm dealing with the following equation: [(a*x)^b]*c=d where ^ stands for XOR and * for Multiplication. How can I isolate x?...

I am converting a vb6 program to c# and I cannot figure out why the results of my exclusive or operation are giving me different values. The vb6 code: 'serialNum = 884167284, and dSize = 1953312760 here' serialNum = serialNum Xor dSize 'serialNum = 1088322956 after this operation' serialNum =...

; This program checks for even or odd parities inside of an array. Displays 1 if even or 0 if odd. Include Irvine32.inc TRUE = 1 FALSE = 0 .data str1 BYTE "Even Parity", 0 str2 BYTE "Odd Parity", 0 str3 BYTE "The block of data under checking is: ",...

I am doing a join and I can't seem to make this XOR to properly work. SELECT t1.COMPANY, t1.MILES, CASE WHEN t2.MILES IS NULL THEN t3.MILES ELSE t2.MILES END AS MILES2, CASE WHEN t2.MILES = t1.MILES AND t2.MILES != 9999 THEN t2.FLATRATE ELSE t3.RATEBASIS END AS RATE FROM TABLE1 AS...

I have two NSData objects, data1 and data2, and I'd like to do a bit-wise XOR and store the result in a third NSData object, xorData. The first thing I tried was this: *data1.bytes^*data2.bytes; but it gave an error of: Invalid operands to binary expression ('const void' and 'const void')...

I'm working on a program which takes a person's name, loops through each character in the name, and combines each character using the XOR command. The program clears the AL register only, NOT the rest of the EAX register.The final XOR result is then stored in the AL register. Code:...

I came across this problem wherein all of the program was given barring only a piece of logic. What could be filled in the following problem's missing lines? Problem Statement Jack and Daniel are friends. They want to encrypt their conversation so that they can save themselves from interception by...

From RFC 5389 Section 15.2: If the IP address family is IPv4, X-Address is computed by taking the mapped IP address in host byte order, XOR'ing it with the magic cookie, and converting the result to network byte order. If the IP address family is IPv6, X-Address is computed by...

I'm trying to learn simple cryptology and as a starter I'm trying to achieve the following. A function, taking two 128 bit params (key and plaintext) as input and returning their XOR. I know XOR is not safe but I'm starting out with a simple example. This is what I...

I have this sample code: #include "stdafx.h" #include "stdio.h" #include "stdlib.h" #include "math.h" #ifndef uint32 #define uint32 unsigned long int #endif #define L(a) printf("\n%x >> 1 = %x", a, a>>1) int _tmain(int argc, _TCHAR* argv[]) { uint32 a = 2941362065; uint32 b = 509727776; uint32 c = a ^ b;...

From a set of divs I want to select all the divs that contain a specific attribute and then select all the divs that do not contain any of the attributes. Example: <div data-attr="1"></div> <div data-attr="2"></div> <div data-attr="3"></div> <div data-attr="4"></div> <div data-attr="5"></div> var attrList = [3,4]; // I want to...

Does the bitwise operator ^= create a temporary variable in memory when it's used? so for a example if I have: a ^= b; Does it create a copy of a in memory, then check against it and then assign? Or does it just straight up check and then assign...
