A custodial staff person at the College does a peculiar thing at night. There is a corridor with a number of lights controlled by toggle switches. Initially all lights are off. Pressing the switch on a light will turn it on. Pressing it again will turn it off. This staff member walks down a corridor with n light n times. On the ith trip the person only toggles the switches whose position number is divisible by i. When coming back to the initial position, the person does not press any switches. Write a program that determines the state (on or off) of the last light in the corridor after the staff member has made n trips up and down the corridor doing this routine Your program should prompt the user for the number of lights in the corridor, read the number and determine and print the value of the last light. You should print an error message if the user does not enter a positive integer. Use a loop for multiple inputs. The loop should terminate when the user enters 0 for the number of lights. Possible sample output: Please enter a positive integer. -3 This is not a positive integer. Please try again. Please enter a positive integer. 3 The last bulb is off. Please enter a positive integer. 0 Have a nice day.

", then output is: dang, that was scary! note: if the submitted code has an out-of-range access, the system will stop running the code after a few seconds, and report "program end never reached." the system doesn't print the test case that caused the reported message.#include #include using namespace std; int main() {string userinput; getline(cin, userinput); int ispresent = userinput. find("darn"); if (ispresent > 0){cout < < "censored" < < endl; /* your solution goes here */return 0; }
