Sample input:

a = 1;
for (b = 2 : 10){
  a = a * b + 2;
  print a;
}

Grammer:

program: statements ;

statements: (statement)+ ;

statement: identifier = expr;
        | { statements }
        | 'if' ( expr ) statement
        | 'if' ( expr ) statement 'else' statement
        | 'while' ( expr ) statement
        | 'for' ( identifier = number : number ) statement
        | 'print' identifier;
