TYL - Food Corner Program

Food Corner Program. We will make this program more robust after you learn try-catch.  For now, we will calculate for only 1 order.  Again, later you can use loops to calculate for many orders.  As we have not learnt any data structures as lists, dictionaries etc, we will not use them now. FoodCorner home delivers vegetarian and non-vegetarian combos to its customer based on order. A vegetarian combo costs Rs.120 per plate and a non-vegetarian combo costs Rs.150 per plate. Their non-veg combo is really famous that they get more orders for their non-vegetarian combo than the vegetarian combo. Apart from the cost per plate of food, customers are also charged for home delivery based on the distance in kms from the restaurant to the delivery point. The delivery charges are as mentioned below: Distance in kms          Delivery charge in Rs. Per kms For first 3 kms                       ...

5 Questions for TYL on Strings(check if two string are anagrams)

Write a program to check if two given strings are anagram or not So an anagram is a  word or phrase formed by rearranging the letters of a different word or phrase, typically using all the original letters exactly once. ( https://en.wikipedia.org/wiki/Anagram ).  It's an essential skill to win at scrabble too. And there are several games you can play on your smart phones as well.  I was pretty addicted to one... look for Anagram Solver. So for example, star Anagram that make sense are : rats, arts, tsar (you get the point right?) But this program is not so strict as to whether the resulting word is meaningful or not, so basically, we're checking if one word contains all the letters in another word. A good starting point would be to check if the length of both the words are the same then proceed from there.  We'll sort it, then check if each letter is the same. You have to decide on a good sorting function to use. sorted is good, it is built in. If yo...
