Missing Observation

CodeChefOpen on judge ↗

Rahul loves doing physics experiments. While doing an experiment, he calculated the Mean $(\bar{x})$ and Standard Deviation $(\sigma)$ of $N$ observations as $X$ and $Y$. On rechecking, he that found that an observation $C$ was miscalculated as $K$. Since Rahul is bad at coding, he asks you to write a code that finds the correct standard deviation $(\sigma_{correct})$. ### Input - The first lin
