Assume the following rules of associativity and precedence for expressions:

precedence
highest
- (unary), (prefix) ++, (prefix) --
(postfix) ++, (postfix) --
+, , & , mod
-, /, not
< , =, > , ! =
=, +=, =, /=

and
or, xor
lowest
associativity
left to right

show the order of evaluation of the following expressions by parenthesizing all subexpressions and placing a superscript on the right parenthesis to indicate order. for example, for the expression a * b + c / d the order of evaluation would be represented as

((a * b)ˆ1 + c)ˆ2 / d)ˆ3

also rewrite the expression where there are no precedence rules and the statement is given right to left associativity, for example for the same problem above

d / c + b * a

a. a * b - 1 + c
b. a * (b - 1) / (++c++) mod d
c. (a - b) / c & (d * e / a - 3)
d. -a or c = d and e
e. a > b xor c or d < = 17
f. -a + b

What is the worst-case complexity of the maxrepeats function? assume that the longest string in the names array is at most 25 characters wide (i.e., string comparison can be treated as o( class namecounter { private: int* counts; int nc; string* names; int nn; public: namecounter (int ncounts, int nnames); int maxrepeats() const; }; int namecounter: : maxrepeats () { int maxcount = 0; for (int i = 0; i < nc; ++i) { int count = 1; for (int j = i+1; j < nc; ++j) { if (names[i] == names[j]) ++count; } maxcount = max(count, maxcount); } return maxcount; }

Given a link with a maximum transmission rate of 32.8 mbps. only two computers, x and y, wish to transmit starting at time t = 0 seconds. computer x sends filex (4 mib) and computer y sends filey (244 kib), both starting at time t = 0. statistical multiplexing is used, with details as follows packet payload size = 1000 bytes packet header size = 24 bytes (overhead) ignore processing and queueing delays assume partial packets (packets consisting of less than 1000 bytes of data) are padded so that they are the same size as full packets. assume continuous alternating-packet transmission. computer x gets the transmission medium first. at what time (t = ? ) would filey finish transmitting? give answer in milliseconds, without units, and round to one decimal places (e.g. for an answer of 0.013777 seconds you would enter "13.8" without the quotes)
