level variables

$*-$ You cannot use switch statements

$*-$ You cannot use the unsigned right shift operator $(>>>)$

$*-$ You cannot use helper methods, call any other methods, or use recursion.

$*$

$*-$ You may not use more than $2$ conditionals per method. Conditionals are

$*$ if$-$statements, if$-$else statements, or ternary expressions. The else block

$*$ associated with an if$-$statement does not count toward this sum.

$*-$ You may not use more than $2$ loops per method. This includes

$*$ for loops, while loops and do$-$while loops.

$*-$ The only Java API methods you are allowed to invoke are:

$*$ String.length$()$

$*$ String.charAt$()$

$*-$ You may not invoke the above methods from String literals.

$*$ Example: $"12345".$length$()$

$*-$ When concatenating numbers with Strings, you may only do so if the number

$*$ is a single digit. Convert a String containing ASCII characters $($in binary$)$ to an int.

$*$

$*$ You do not need to handle negative numbers. The Strings we will pass in

$*$ will be valid binary numbers, and able to fit in a $32-$bit signed integer.

$*$

$*$ Example: binaryStringToInt$("110")$; $//=>6$

$*/$

public static int binaryStringToInt$($String binary$)\{$

return $0$;
