**Javascript staircase problem**.
Observe that its base and height are both equal to n and the image is drawn using symbols and spaces.
Staircase problem statement consider a staircase of size n 4.
Call the function recursively with values n 1 n 2 and n 3 and sum up the values that are returned i e.
Given n write a function that returns the number of unique ways you can climb the staircase.

Consider the above figure to be a set of 7 received blocks of bits from the bsc. In how many distinct ways can you climb to the top. Print a right aligned staircase with n steps. Each time you can either climb 1 or 2 steps.

Of lines in output is equal to height of the staircase. For the generalization of above approach the following recursive relation can be used. It takes n steps to reach to the top. Generalization of the problem how to count the number of ways if the person can climb up to m stairs for a given value m.

You are climbing a stair case. A common algorithm found in technical interviews is the climbing staircase problem. Each time you can either climb 1 or 2 steps. Let s work through the following problem.

Since every line is nearly the same and only one character changes at a time you should take advantage of that and use an array as a buffer. The order of the steps matters. Of hashes in last line is equal to the height of staircase. Such a decoder is referred to as a sliding window decoder.

If the value of n is less than 0 then return 0 and if the value of n is equal to zero then return 1 as it is the starting stair. There exists a staircase with n steps and you can climb up either 1 or 2 steps at a time.

For example if m is 4 the person can climb 1 stair or 2 stairs or 3 stairs or 4 stairs at a time. Input n as the height of the staircase draw a staircase with the given height. Given n will be a positive integer. Today s algorithm is the climbing stairs problem.

Staircase codes are decoded by using an iterative decoder operating over several received blocks. For example if the input were 2 there s 2 stairs in the staircase then there are 2 distinct ways to climb to the top. The decoder will operate over these blocks shift out a decoded block and shift in a newly received block. It takes n steps to reach to the top.
