Fidn the value

BEGIN

    Prompt User to enter a certain amount of numbers

    Set d as amount of numbers in the list

    Set k as test variable

    Assign a value v to k

    Assign k to drop down the list d amount of times

    For each variable check if k encounters a d that is the same value

    loop d amount of times.

    If k = v then return yes

    If k != v then return no

END

This will work because when k goes down the list it either will or will not encounter a v that is the same value.

This will end because when program reaches d amount of times the program will end.
