This is a caesar encryption code, please help me with a code to reverse this operation (decrept it) in C++ string encrypt(string text, int s){ string result = ""; // traverse text for (int i=0;i<text.length();i++) { // apply transformation to each character // Encrypt Uppercase letters if (isupper(text[i])) result += char(int(text[i]+s-65)%26 +65); // Encrypt Lowercase letters else result += char(int(text[i]+s-97)%26 +97); } // Return the resulting string return result;} int main(){ string text; int s; cin>> text; cin >> s; cout << "Text : " << text; cout << "\nShift: " << s; cout << "\nCipher: " << encrypt(text, s); return 0;}
Assume that nextWord is a String variable that has been given a String value consisting entirely of letters. Write some Java code that outputs the message "First half of the alphabet", provided nextWord precedes "N" in alphabetic ordering. If nextWord does not precede "N" in alphabetic ordering, the code should output "Second half of the alphabet". (Note that "N" uses double quotes to produce a String value, as opposed to using single quotes to produce a char value.)

Given three int variables that have been given values, areaCode, exchange, and lastFour, write a string expression whose value is the string equivalent of each these variables joined by a single hyphen (-) So if areaCode, exchange, and lastFour, had the values 800, 555, and 1212, the expression's value would be "800-555-1212". Alternatively, if areaCode, exchange, and lastFour, had the values 212, 867 and 5309 the expression's value would be "212-867-5309".

Write a program that allows the user to enter a number between 1 and 1000. If the number is invalid, provide an error message and allow the user to try again until he enters a valid value. Once you have a valid number, use it to determine and print the following information: *Note that in the list of factor pairs, you should not include duplicates. program in python Number squared Number cubed Number Type: Even composite numberOdd or Even Prime (Exactly 2 factors) or Composite (More than 2 factors) Whether the number is a perfect square: No (6 does not have an integer square root like 4 or 9) Square Root: (Print this line only if the number is perfect square) List of factors that exclude duplicates and are printed horizontally on a single lineFactors: (1, 12) (2, 6) (3, 4) (4, 3) (6, 2) (12, 1) should not be included
In python, write a code that allows the user to input two non-negative number sequences in increasing order (the numbers entered are always getting bigger, and no number repeats), both terminated by a -1. The size of each sequence can vary (maybe sequence - 1 has four numbers, and sequence - 2 has seven). The output of this code should be a third sequence that is a combination of both sequences 1 and 2 and is sorted in non-decreasing order. Note: Non-decreasing order means there can be a repeated number in the third sequence (see example 1). A strictly increasing order sequence cannot have repeat numbers at all (see example 3). Remember, all input sequences must be in strictly increasing order! please do this using python, only using while loops. NO language of "break" or "len" please. Hint: we can use three separate lists to solve this code.
Hi in the below code I would like to remove the blank tokens and how to achieve it. #include <stdio.h> #include <string.h> #include <stdlib.h> int count_tokens(const char* str) { int count = 0; int invalidToken = 0; // set false for(int i = 0; i <= strlen(str); i++) { if( i == strlen(str) || str[i] == 32){ // if past end of string, or if space if(invalidToken) { invalidToken = 0; // set false continue; } else { count++; // increment count only if token was not invalid continue; } } if( !(str[i] >= 97 && str[i] <= 122) ) { // if not lowercase letter invalidToken = 1; // set true } } return count; } char** split_tokens(const char* str) { char **tokenArr; tokenArr = (char **) malloc(count_tokens(str) * sizeof(char*)); /*use count_tokes() to determine the length*/ int…
A substring in programming represents all characters from a string, between two specified indices. Given a variable string called seq, a student writes the following program that will generate all nonempty substrings of seq: for i in range(len(seq)) : # line 1 for j in range(i) : # line 2 print(seq[j:i]) # line 3 Which of the following changes make the above program correct? A. Program is correct as it is. B. Change line 1 to: for i in range(len(seq)+1) : C. Change line 3 to: print(seq[j:i+1]) D. Change line 2 to: for j in range(i+1) :
Many companies use telephone numbers like 555-GET-FOOD so the number is easier for their customers to remember. On a standard telephone, the alphabetic letters are mapped to numbers in the following fashion:A, B, and C = 2D, E, and F = 3G, H, and I = 4J, K, and L = 5M, N, and O = 6P, Q, R, and S = 7T, U, and V = 8W, X, Y, and Z = 9Create an application that lets the user enter a 10-character telephone number in the format XXX-XXX-XXXX. The application should display the telephone number with any alphabetic characters that appeared in the original translated to their numeric equivalent. For example, if the user enters 555-GET-FOOD, the application should display 555-438-3663.
