Matching parentheses. An math expression may have a number of parentheses like (, ), [, ], { and }. Each openning parenthesis (, or [, or { must be macthed by a corresponding closing parenthsis ), or ] or }. For example, 12 { 34 / [ 6 * ( 55 - 10 ) / ( 100 20 ) ] } has matched pairs of parentheses, while 12 { 34 / ( 6 * ) ] } does not. Write a function to check whether an input math expression has matched parentheses. The header of the function is given as follows:
bool match( const char exp [ ], const int s);
The input math express is store in the char array exp, and the size of exp is s. It returns true if all parentheses are matched or false otherwise.

Answer:

An Intrusion Detection System (IDS) is a system that monitors network traffic for suspicious activity and issues alerts when such activity is discovered. It is a software application that scans a network or a system for harmful activity or policy breaching. Any malicious venture or violation is normally reported either to an administrator or collected centrally using a security information and event management (SIEM) system. A SIEM system integrates outputs from multiple sources and uses alarm filtering techniques to differentiate malicious activity from false alarms.

You are given an array of integers. Your task is to create pairs of them, such that every created pair has the same sum. This sum is not specified, but the number of created pairs should be the maximum possible. Each array element may belong to one pair only.

Write a function

class Solution public int
solution (int[] A); }

that, given an array A consisting of N integers, returns the maximum possible number of pairs with the same sum.

Examples:
1. Given A = [1, 9, 8, 100, 2], the function should return 2. The pairs are (A[0]. A[1]) and (A[2], A[4]); the sum of each pair is 10.
2. Given A = [2, 2, 2, 3], the function should return 1. Although, for instance, A[0]+A[1] = A[0]+A[2], the pairs (A[0], A[1]) and (A[0], A[2]) cannot exist at the same time, because they both contain a common element, A[0].

Answers

Complete PYTHON code with explanation:

def solution(nums):

# form a dictionary which will store

# the possible pair's sum as key and the indexs used for the sum

sumAndpair = {}

# for every element in list nums

for i in range(len(nums)):

# iterate on all the element to the right of current element

for j in range(i+1,len(nums)):

# calculate the sum of current 2 elements

sum = nums[i] + nums[j]

# if the sum is already in the dictionay

if sum in sumAndpair:

# check if the current index have already been used

# if yes, then continue to next iteration

# this will make sure that same number have not been used more than once

if i in sumAndpair[sum] or j in sumAndpair[sum]:

continue

# if no, then append the current i and j to the value of current sum

else:

sumAndpair[sum].append(i)

sumAndpair[sum].append(j)

# if the current sum is not in the dictionary

# add the sum as key with a list of index used

else:

sumAndpair[sum] = [i, j]

# copmpute the maximum possible number of pairs with the same sum

# which will be the maximum length value out of all the possible sum

# this maximum length will be divided by 2, since a pair of i, j contrinute to one sum

PLEASE HELP ILL GIVE A HEART AND 5 STARS In Canada, just like in China, eating at McDonalds was a novelty for us. In the wake of post-Mao economic reforms, the belated introduction of the Golden Arches to China represented a whole ethos about what constituted the good life. Fast food might connote easy accessibility or overindulgence in the West, but McDonalds presented a different kind of comfort for my family and me. The cost of a burger was hardly a trivial thing for us at the time, and my parents didnt actually treat me to meals there all that often. When they did, we always got takeout so we could eat our burgers and fries around our Formica dining table, on our own plates. The hope was to have our fast food as slowly as we could. The Filet-O-Fish became my menu item of choice. Its virtues are too many to count; doing so would be futile. As McDonalds only seafood-based option, the Filet-O-Fishs semblance of relative health appealed to my parents. Luckily it was also McDonalds most delicious item. It played to my Chinese palate: While other McDonalds buns were toasted, the Filet-O-Fishs was steamed, much like the baozi2. From its honeyed starch to its tangy tartar and savory fillet, the taste of the Filet-O-Fish carries an ineffable umami-ness. At once sweet and sour, it reminds me of orange-chicken sauce: a plausibly Chinese flavor mass-produced in America. Eating one always felt transportive the equivalent of Prousts madeleine3 for my Chinese diasporic upbringing. The Filet-O-Fish is the gold standard of fast food for many Asian-Americans, as well as other minority American communities. Invented by an Ohio franchise owner in 1962, the first Filet-O-Fish was the answer to the problem of McDonalds falling sales on Fridays, when observant Catholics abstained from eating meat. Born from an attempt to market fast food to as many people as possible, the tasty little unit has since been further claimed by everyone from fish-loving Chinese-Americans to practicing Muslims to well, anyone with taste. By 1965 the sandwich had gone national. Its appeal is inscrutable, perhaps out of proportion to its paltry constituent parts. Consider the recognizably flaky fish patty, made from the ubiquitous Alaskan pollock. Pollock is everywhere, writes the marine fisheries biologist Kevin M. Bailey in the book Billion-Dollar Fish. It is the pure white meat in fish sticks bought at Walmart and Filet-O-Fish burgers ordered in McDonalds. But you wouldnt want the fish to be more interesting. The generic quality of pollocks fishiness common enough for various cuisines to lay claim to it is part of its allure. So maybe what makes the sandwich beloved isnt its taste at all, but the juxtaposition of its elements: A single fillet of fried fish, topped with a thin slice of American cheese and tartar sauce, all of it cradled in a bun whose impossible roundness suggests the triumph of industrial food production. As a child, I was under the fantasy that my obsession with such a strange sandwich was eccentric. When I went to McDonalds with friends who got Chicken McNuggets Happy Meals or cheeseburgers, ordering the Filet-O-Fish made me feel as if I was in on some sort of secret. After a few years in Montreal, my dad landed a good government job in Victoria, British Columbia. On our drive across Canada, we indulged in the prospect of my dads earning a real salary by eating at McDonalds almost daily, a whirlwind of Filet-O-Fish meals (for me) and hamburgers (for my parents). But my experience was shattered when I, fancying myself different, pointed out that my parents both loved hamburgers while I, a renegade, preferred the Filet-O-Fish. Well, I like the Filet-O-Fish most too, my mother put it candidly. But it is expensive, so we only buy it for you. These days, the sandwich is more expensive than ever; its also less beautiful than I remember. At some point, the Filet-O-Fish underwent rebranding: An ostentatious paper box replaced the modest blue wrapper, while what I remember being a full slice of cheese seems to have shrank by half. McDonalds insists that the cheese has always been half a slice so as not to overwhelm the fishiness of the fillet. Todays unboxing experience most often reveals limp cheese sagging off the patty, frequently stuck to the ill-advised box. Where is the madeleine of my youth? Nowadays, a good Filet-O-Fish is hard to find.
