Linked lists use dynamic memory allocation i.e. they grow and shrink accordingly. They are defined as a collection of nodes. Here, nodes have two parts, which are data and link. The representation of data, link and linked lists is given below −Operations on linked listsThere are three types of operations ... Read More

Standard deviation is used to measure deviation of data from its mean. The mathematical formula to calculate the standard deviation is as follows −$$s=\sqrt{Variance}$$whereVariance$$=\frac{1}{n}\:\:\displaystyle\sum\limits_{i=1}^n (x_{i}-m)^{2}$$and$$m=mean=\frac{1}{n}\:\displaystyle\sum\limits_{i=1}^n x_{i}$$AlgorithmRefer an algorithm given below to calculate the standard deviation for the given numbers.Step 1 − Read n items.Step 2 − Calculate sum and mean ...
