- Q After many such encounters of the SENIOR kind, finally you feel that things are in order and the gentle smile, though mellowed with bitter experience, is still there. But a week's over, and so is your stock of undies, which number 7 (seven). You have realised that now you need to wash them! (Becoz Mommy insists that you wear a clean pair of undies every day.) But now you have had a taste of an IITian's life: too many things to do, too less time. So following Mommy's advice, you decide to plan out things. You know your routine now, so you know exactly what days you will be able to do the washing and what days you won't. You decide 2 things: 1> Since the number of undies is 7 (seven), the washing dates can atmost be separated by 7. Thus, if you wash on the 15th, you have to wash on or before the 22nd. 2> Since basically you are a lethargic bum, you decide that you will wash only if you have atleast 2 dirty undies to wash. Thus the dates must be separated by atleast 3. (So you have to wash on or after 18th, if you wash on the 15th) Since, as mentioned above, you are a lethargic bum, you want to find out the MINIMUM number of days you need to have a fresh undie every day to wear. You also know the number of days you have to spend, and the possible washing days. Input: The total number of days(N) on the first line. The total number of washing days(M) on the second line. The dates of the washing days, M of them, one on each line. NOTE: The dates are numbered from 0 to (N-1). Assume that you start out with a fresh set of undies BEFORE 0th day, (i.e the -1th day), so you need to wash on or before 6th, but but not before the 2nd day. Output: The minimum number of days you need to do the washing. Just the number, on a line by itself. Output -1 if it is impossible to schedule washing days subject to the conditions. Sample Input: 10 4 0 3 6 9 Sample Output: 1 (Since you can wash on the 6th This was an error earlier). length of input > strings? could be at max 100000.
- Q A 35-year-old man presented with a history of progressive difficulty in swallowing over the last 12 months. Initially he had difficulty swallowing solid food but since the last month the ability to swallow liquids had diminished as well, and swallowing was associated with chest pain. Upper gastrointestinal (GI) series revealed the presence of a dilated esophagus with a bird beak like narrowing of the lower end of the esophagus. Upper GI endoscopy did not reveal any mucosal abnormality. Discuss the pathophysiologic mechanisms underlying this presentation.
