strings (kthe string with every letter replaced by space simple way to estimate the number of words in string is to count the number of spaces in the string write program that asks the user for string and returns an estimate of how many words are in the string people often forget closing parentheses when entering formulas write program that asks the user to enter formula and prints out whether the formula has the same number of opening and closing parentheses write program that asks the user to enter word and prints out whether that word contains any vowels write program that asks the user to enter string the program should create new string called new_string from the user' string such that the second character is changed to an asterisk and three exclamation points are attached to the end of the string finallyprint new_string typical output is shown belowenter your stringqbert *ert!! write program that asks the user to enter string and then converts to lowercaseremoves all the periods and commas from sand prints the resulting string write program that asks the user to enter word and determines whether the word is palindrome or not palindrome is word that reads the same backwards as forwards at certain schoolstudent email addresses end with @student college eduwhile professor email addresses end with @prof college edu write program that first asks the user how many email addresses they will be enteringand then has the user enter those addresses after all the email addresses are enteredthe program should print out message indicating either that all the addresses are student addresses or that there were some professor addresses entered ask the user for number and then print the followingwhere the pattern ends at the number that the user enters write program that asks the user to enter stringthen prints out each letter of the string doubled and on separate line for instanceif the user entered heythe output would be hh ee yy
