Leokris [45]

Using the knowledge in computational language in C++ it is possible to write a code that cryptarithm is a mathematical puzzle where the goal is to find the correspondence between letters and digits

<h3>Writting the code:</h3>

#include <bits/stdc++.h>

using namespace std;

// chracter to digit mapping, and the inverse

// (if you want better performance: use array instead of unordered_map)

unordered_map<char, int> c2i;

unordered_map<int, char> i2c;

int ans = 0;

// limit: length of result

int limit = 0;

// digit: index of digit in a word, widx: index of a word in word list, sum: summation of all word[digit]

bool helper(vector<string>& words, string& result, int digit, int widx, int sum) {

if (digit == limit) {

ans += (sum == 0);

return sum == 0;

}

// if summation at digit position complete, validate it with result[digit].

if (widx == words.size()) {

if (c2i.count(result[digit]) == 0 && i2c.count(sum%10) == 0) {

if (sum%10 == 0 && digit+1 == limit) // Avoid leading zero in result

return false;

c2i[result[digit]] = sum % 10;

i2c[sum%10] = result[digit];

bool tmp = helper(words, result, digit+1, 0, sum/10);

c2i.erase(result[digit]);

i2c.erase(sum%10);

ans += tmp;

return tmp;

} else if (c2i.count(result[digit]) && c2i[result[digit]] == sum % 10){

if (digit + 1 == limit && 0 == c2i[result[digit]]) {

return false;

}

return helper(words, result, digit+1, 0, sum/10);

} else {

return false;

}

// if word[widx] length less than digit, ignore and go to next word

if (digit >= words[widx].length()) {

return helper(words, result, digit, widx+1, sum);

}

// if word[widx][digit] already mapped to a value

if (c2i.count(words[widx][digit])) {

if (digit+1 == words[widx].length() && words[widx].length() > 1 && c2i[words[widx][digit]] == 0)

return false;

return helper(words, result, digit, widx+1, sum+c2i[words[widx][digit]]);

}

// if word[widx][digit] not mapped to a value yet

for (int i = 0; i < 10; i++) {

if (digit+1 == words[widx].length() && i == 0 && words[widx].length() > 1) continue;

void isSolvable(vector<string>& words, string result) {

limit = result.length();

for (auto &w: words)

if (w.length() > limit)

return;

for (auto&w:words)

int main()

Session Hijacking refers to the exploitation of a valid computer session where an attacker takes over a session between two comp

noname [10]

Answer:Weak session ID generation algorithm

Explanation: Session hijacking is the hacking by disguising as the authenticated user and illegally exploit the particular computer session. IP packets are invoked by the disguised attacker into the active session between the legal computer user. It is also called session key.

It gives the hacker to use the data and services of the computer in an unauthorized manner. It arises due to the session of communication are not secure and strong,key used for session is weak etc.

Implement a function named largerThanN that accepts three arguments: an array of type int, the size of the array of type int and

levacccp [35]

Answer:

import java.util.Scanner;

public class NewArray {

//Main Method begins here

public static void main(String[] args) {

int [] numbers = {30,20,50,2,-1,44,3,12,90,32}; //The given array

Scanner in = new Scanner(System.in);

System.out.println("enter a number");

int n = in.nextInt(); //Receive the number from the user

//Calling the method largerThanN

largerThanN(numbers, numbers.length,n);

}

//The method largerThanN begins here

public static void largerThanN(int []intArray, int arraySize, int n){

for(int i = 0; i < intArray.length; i++){

if(intArray[i] > n){

System.out.println(intArray[i]);

}

Explanation:

Uisng the Java prograamming language the solution is provided above.

Please see the comments within the code for detailed explanation

The key logic within the method largerThanN () is using a for loop to iterate the entire array. Within the for loop use an if statement to compare each element with the the number n entered by the user
