1) String format checker A string is referred to as A"B"A" if it contains n > 0 consecutive As followed by n consecutive Bs followed by n consecutive As. Your task is to accept an arbitrary string of any length 1 <k, and determine if it is of the form A"B"A" If it is, then the output of the program is be "Format is OK". Otherwise the output is "Format not acceptable." For example, The given the Linux prompt>...
