Suppose you went to a coffee shop and you want to drink some coffee. You decided to drink n cup of coffee, where n is an integer value greater than 0. Now you have to pay m taka for the first cup of coffee, 2m taka for the second cup, 3m takas for the third cup, and so on. In other words, you have to pay i*m taka for the i-th cup of coffee. Now you have k taka in your pocket. How many takas do you need to borrow from your friend to buy n cup of coffee? The first input in the sample input contains the cost of the first cup of coffee which can be denoted as m. The second input is the number of coffees you want to drink, n. The third input is k, the initial amount of taka you have. You have to calculate how much money you have to borrow from your friend. If you have more or equal amount of money that is needed than print 0. Sample Input 1: 3 5 15 Sample Output 1: 30 Explanation 1: Here the price of the first cup of coffee is 3 taka and you want to drink 5 cups of coffee. So you will need a total of 3 + 6 + 9 + 12 + 15 = 45 tk. But you have 15 tk in your pocket. So you have to borrow 45 - 15 = 30 taka from your friend.

Create a web form to help in creating simple random passwords. Your web form should have four text fields named Field1, Field2, Field3, and Field4, as well as “Reset” and “Submit” buttons. You need to create a separate PHP form-processing script that verifies that all four words are entered, that all of them contain only letters, and that all four are between 4 and 7 characters long. Once all of the words have been verified as correct, use the strtoupper() and str_shuffle() functions to produce four suggested jumbled sets of passwords using the words entered in the text fields Note: you need to perform the validation on the server side using PHP scripts. use the preg_match() function to check for letters
