Given with a positive integer value let’s say ‘val’ and the task is to print the value of binomial coefficient B(n, k) where, n and k be any value between 0 to val and hence display the result.What is Binomial CoefficientBinomial coefficient (n, k) is the order of choosing ‘k’ results from the given ‘n’ possibilities. The value of binomial coefficient of positive n and k is given by$$C_k^n=\frac{n!}{(n-k)!k!}$$where, n >= kExampleInput-: B(9, 2) Output-:$$B_2^9=\frac{9!}{(9-2)!2!}$$ $$\frac{9\times 8\times 7\times 6\times 5\times 4\times 3\times 2\times 1}{6\times 5\times 4\times 3\times 2\times 1)\times 2\times 1}=\frac{362, 880}{1440}=252$$What is Binomial Coefficient TableThe Binomial Coefficient Table is formed ...

Given an interger n; the task is to find the Catalan Number on that nth position. So, before doing the program we must know what is a Catalan Number?Catlan numbers are the sequence of natural numbers, which occurs in the form of various counting number problems.Catalan numbers C0, C1, C2, … Cn are driven by formula −$$c_{n}=\frac{1}{n+1}\binom{2n}{n} = \frac{2n!}{(n+1)!n!}$$The few Catalan numbers for every n = 0, 1, 2, 3, … are 1, 1, 2, 5, 14, 42, 132, 429, 1430, 4862, …So if we entered n =3 we should get 5 as an output from the programSome of few ...

Given a number as a string and a base; the task is to check whether the given number of is of that given base or not.We have to check the number and the base according to the number system in which there are bases like 2 for a binary number, 8 for an octal number, 10 for decimal number and 16 for a Hexadecimal number. According to this we have to find whether the given number in a string belongs to a particular base or not, If it belongs to a particular base then we have to print “Yes” on ... Read More

Given ‘a’ the First term, ‘d’ the common difference and ‘n’ for the number of terms in a series. The task is to find the nth term of the series.So, before discussing how to write a program for the problem first we should know what is Arithmetic Progression.Arithmetic progression or arithmetic sequence is a sequence of number where the difference between the two consecutive terms is same.Like we have first term i.e a =5, difference 1 and nth term we want to find should be 3. So, the series would be: 5, 6, 7 so the output must be 7.So, ... Read More

Given ‘a’ the First term, ‘r’ the common ratio and ‘n’ for the number of terms in a series. The task is to find the nth term of the series.So, before discussing how to write a program for the problem first we should know what is Geometric Progression.Geometric progression or Geometric sequence in mathematics are where each term after the first term is found by multiplying the previous one with the common ratio for a fixed number of terms.Like 2, 4, 8, 16, 32.. is a geometric progression with first term 2 and common ratio 2. If we have n ... Read More

Given an Url address of any website; the task is to calculate the round trip time of a website.Round Trip Time(RTT) is the total time or the length of a time which is taken to send a signal plus the time taken to receive the acknowledgement of that signal to be received. This time also consist of the propagation times between two points of a signal.An end user can determine his/her round trip time from an IP address by pinging that address.The Round Trip time’ result depends upon the following reasons −The Transmission medium.The presence of Interface in the circuit.Number ...

Given RGB color range in form of integers; the task is to find its appropriate HSV color by converting the RGB color rangeWhat is RGB color modelRGB color model comprised of three colors Red, Green and Blue. RGB model is a color model which is widely used in the display technologies; it is an additive model in which we add these three colors of with different intensities to produce millions of different colors on a display device.What is HSV color model?HSV color model comprises Hue, Saturation, Value also known as HSB (Hue, Saturation, Brightness).HSV is alternative representation of RGB color ...
