String personName is read from input. Output personName left aligned with a width of 6, followed by " Taylor". End with a newline. Ex: If the input is Juno, then the output is: Juno Taylor Use Java
Read string integer value pairs from input until "Done" is read. For each string read: • If the following integer read is less than 40, output the string followed by ": low on stock". • Otherwise, output the string followed by ": well stocked". End each output with a newline. Ex: If the input is Oven 43 Curtain 7 Pillow 1 Done, then the output is: Oven: well stocked Curtain: low on stock Pillow: low on stock 1 #include 2 #include 3 using namespace std; 4 5 int main() { 6 7 8 9 10 } * Your code goes here */ return 0;

6. A palindrome is a number or text phrase that reads the same backwards or forwards. For example, each of the following five-digit integers is a palindrome: 12321, 55555, 45554 and 11611. Write a program that reads a 5 digit integer and determines whether it is a palindrome. Hint: One way to do this is to use division (/) and modulus (%) operators to separate the number into individual digits.
Assign Barbecue's data member numberOfCalories with a value read from input. Then, assign Ham and Cheese's data member numberOfCalories with another value read from input. Input will contain two integer numbers. Only the *your code goes here can be affected, the rest of the program cannot be changed.

Aim: Read a string, S and print its integer value. If S cannot be converted to an integer, print Bad String. ''' # getting the input S = input().strip() try: # if it's possible to convert the entered string into an integer then this block will execute print(int(S)) except: # if it's not possible, then this block will be executed print('Bad String') ''' COMPLEXITY: Time Complexity -> O(1) Space Complexity -> O(1) Sample Input 1: 3 Sample Output 1: 3 Sample Input 2: SB Sample Output 2: Bad String Explaination: '3' as a string can be converted into the integer 3, whereas SB can't be converted to an integer hence the 'except' block is executed and 'Bad String' is printed.
