simple java task needed

A simple code to be converted to a Psuedo code Here's my code, I need to rewrite it into functional language.. it should be pretty easy assignment, thus the deadline is only a day. #include<iostream> using namespace std; // function that returns absolute difference between 2 numbers // input is a int absoluteDiff(int a) { // variable declaration int b = 4; // condition if(a>b) return a-b; else return b-a; } main(){ // 2 sample runs cout << absoluteDiff(2) << endl; cout << absoluteDiff(8) << endl; } /*SAMPLE OUTPUT 2 4 */ and here's an example of functional language to which above code should be transformed to: function isFive a: integer returns boolean; b: boolean is false; begin if a==5 then !b; else b; endif; end; The program will return false for any input not equal to 5 and it will return true for an input equal to 5.
