# Javascript Staircase Problem

**Consider the above figure to be a set of 7 received blocks of bits from the bsc.**

**Javascript staircase problem**.
Print a right aligned staircase with n steps.
Observe that its base and height are both equal to n and the image is drawn using symbols and spaces.
Let s work through the following problem.
Each time you can either climb 1 or 2 steps.

Sum count n 1 count n 2 count n 3 return the value of the sum. Staircase codes are decoded by using an iterative decoder operating over several received blocks. You are climbing a stair case. Input n as the height of the staircase draw a staircase with the given height.

Of lines in output is equal to height of the staircase. The order of the steps matters. A common algorithm found in technical interviews is the climbing staircase problem. Given n will be a positive integer.

There exists a staircase with n steps and you can climb up either 1 or 2 steps at a time. 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. Staircase problem statement consider a staircase of size n 4. 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.

Given n write a function that returns the number of unique ways you can climb the staircase. Today s algorithm is the climbing stairs problem. Of hashes in last line is equal to the height of staircase. Please read our cookie policy for more information about how we use cookies.

Javascript function names should start with a lowercase character and staircase is one compound word in english. 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. Call the function recursively with values n 1 n 2 and n 3 and sum up the values that are returned i e.

For the generalization of above approach the following recursive relation can be used. 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. It takes n steps to reach to the top. For example if m is 4 the person can climb 1 stair or 2 stairs or 3 stairs or 4 stairs at a time.
