Write a single statement that shifts row array attendancevalues one position to the left. the rightmost element in shiftedvalues also keeps its value.
ex: [10, 20, 30, 40] after shifting becomes [20, 30, 40, 40]

Hi, you haven't provided the programing language in which you need the code, I'll just explain how to do it using Matlab, and you can apply a similar method for any programming language.
