In sololearn, you need to write all the input values before compiling starts. You're only giving the size, and program isn't going to stop n popup input-field for arrays input. If you're giving size 5, then give the 5 values too. For eg, 5 1 2 3 4 5 1st num is the size, the next 5 are values for array!
