boat 1 arrives any time within a_1 minutes
boat 2 arrives any time within a_2 minutes
...
boat N arrives any time within a_N minutes (uniform distribution)
Tell discord the expected number of minutes he needs to wait for a boat to arrive.
For example If n=3 , and there arriving times are 49,50,51 respectively then expected number of minutes would be 12.495000 . Thats all I know .

user-id page-type-id
User IDs are arbitrary strings that uniquely represent a given user; if a user visits multiple pages, each log entry will have the same user ID. Page type IDs are arbitrary strings that uniquely represent a given kind of page on our site, such as the homepage, a product detail pages, or the shopping cart. Tons of users visit our website, but there are only a few dozen types of pages.
We can use our weblogs to answer questions about user b...

Q4
Staves
You want it to be composed of two smaller staves of equal length so that you can either use it as a single staff or as two smaller ones.
You want the full sized staff's center of gravity to be exactly in the middle of the staff.
You have a very, very long branch from which you can cut the pieces for your
staff. The mass of the branch varies significantly throughout it, so you use
just any two pieces of the same length. Given a description of the mass
throughout the branch, determine the longest staff you can make, then return
three integers on a single line, the first two indicatin...

Q6
Given a 2-D MxN matrix having each value as difficulty for the block
struct node { int x; int y; struct node *next; };
struct path { int difficulty; struct node *pathlink; }
Ex matrix - 4X4 matrix
7 9 2 11 13 23 1 3 14 11 20 6 22 44 3 15
Minimum difficulty = 7 (a[0][0])+ 2(a[0][2]) +3(a[3][2])+15(a[3][3]) = 27 Path trace will have = 7->2->3->15

Facebook interview question
Two players are plaing a game. There is number n written on a black board. The game is played as following:
Each time a player chooses an integer number (0 <= k) so that 2^k is less than n and (n-2^k) has as beautiful as n. Next he removes n from blackboard and writes n-2^k instead. The player that can not continue the game (there is no such k that satisfies the constrains) looses the game.
The First player starts the game and they play in turns alternatively. Knowing that both two players play optimally you have to specify the winner.
Input:
First line of the Input contains an integer T, the number of testcase. 0 <= T &...
