Java, finish the recursive function that converts a binary string to decimal, do not change main or function header.

public static void main( String[] args ) { if( binToDec( "1101100" ) == 108 ) { System.out.println( "binToDec1 is correct!" ); } if( binToDec( "1011101" ) == 93 ) { System.out.println( "binToDec2 is correct!" ); }

}

public static int binToDec( String bin ) {

}
