| Complexity T(n)
Write a linear-time algorithm that sorts n distinct
integers, each of which is between 1 and 500.
Hint: Use a 500-element array. (Linear-time means your
algorithm runs in time c*n + b, where c and b are any
constants that do not depend on n.
For example, your algorithm can run in time n, or time 2n +
1, or time 5n + 10, or time 100n + 6, but not time c*n*n =
c*n?.) | Qatar-University | 1 |

| Algorithm in O(2n)
Presently we can solve in our hypothetical machine problem
instances of size 100 in 1 minute using algorithm A, which
is a O(2n). We would like to solve instances of size 200 in
1 minute using algorithm A on a new machine.
What is the speed of the new machine should be? | Qatar-University | 2 |
| Counting in Lojban, an artificial language developed over
the last fourty years, is easier than in most languages
The numbers from zero to nine are:
0 no
1 pa
2 re
3 ci
4 vo
5 mk
6 xa
7 ze
8 bi
9 so
Larger numbers are created by gluing the digit togather.

a no less than or equal to 1,000,000) and output it in
numbers.

| write a c program, using for loop, that accepts and odds two
numbers. The output must be the sum and the addens. This
should be repeated 5 times while the first number is
decremented by one and the second number is incremented by 1.

| hello friends, given an expression we have to remove the
unwanted brackets in that expression.
Eg : (a+b) ---> a+b
(a+b)*(c)-----> (a+b)*c. Please mail me if you know
the logic. My mail id is : saravana6m@gmail.com.

| Where now stands that small knot of villages known as the
Endians, a mighty forest once stood. Indeed, legand has it
that you could have stoodon the edge of the wood and seen
it stretch out for miles, were it not for the trees getting
in the way.
In one section of the forest, the trees stood in a row and
were of hight from 1 to n, each hight occurring once and
once only.
A tree was only visible if there were no higher trees
before it in the row.
For example, if the heights were 324165, the only visible
trees would have been those of height 3,4 & 6.
Write a Program that takes an array of integers
representing the heights of the trees in the row as input
and prints the list of the visible trees.
