Problem $1$: Write input $/$ output $/$ relevant formula and sequence of instructions in simple English $($pseudocode$)$ to find and output the last digit of a given number. For example, if the given number is $398,$ its last digit is $8.$ If the given number is $398\mathrm{.}45,$ then its last digit is $5.$

Note that that the given number can be either a whole number $($e$.$g$.,398)$ or a real number $($e$.$g$.,398\mathrm{.}45).$ For this problem, assume that real numbers have exactly $2$ digits after decimal.
