The Signature of third parameter is not completely visible , dont know why. Its void foo(int a, int b, Func algo)

The Signature of third parameter is not completely visible , "Func algo"

We know that Function passes in 2 template types T and R. T extends Number/Integer and since the number is passed to the algorithm to check for completeness. If you define complete to be true false then R is Boolean or extends Boolean. If not then you have to ask for a definition of complete. Assuming completeeans boolean true then: void f(int a, int b, Function func) { int start = a
