My input:
10
15
20

My desired output:
Median = 15


**From the three figures in above, I know that 15 is the median. How can I use the UNIX command line to find it out automatically? My senior is advised me can use the 'awk' command line and the 'if' 'else' condition at the same time. Hope any UNIX expert can help me solve this problem. Really thanks a lot for your help.
