How do you increase the number of tries by one?

LenKa [72]

Answer:

tries = tries + 1

Explanation:

This is a universal way to increment your variable. In some languages, the following notation also works:

tries++;

tries += 1;

Again, it depends upon the language you are using. Each language has it's own syntax.

Write a function "nonRepeatings" that takes a string "s3" and returns the non-repeating characters in this string. Sample Input

Furkat [3]

Answer:

def nonRepeatings(s3):

non = []

letter_dictionary = {}

for l in s3:

if l in letter_dictionary:

letter_dictionary[l] += 1

else:

letter_dictionary[l] = 1

for c in letter_dictionary:

if letter_dictionary[c] == 1:

non.append(c)

return non

Explanation:

- Declare an empty list and a dictionary

- Initialize a for loop that iterates through the given string s3

Inside the loop:

- If a character in the string is in the dictionary, increment its count by 1. If not, add it to the dictionary

When the first loop is done, initialize another for loop that iterates through the dictionary.

- Inside the loop, check if any character has a value of 1, put it to the non.

- Finally, return the non

Have the javascript function CountingMinutes(str) take the str parameter being passed which will be two times (each properly for

jarptica [38.1K]

Using the knowledge in computational language in Java it is possible to write a code that function as CountingMinutes:

<h3>Writing the code in Java:</h3>

function CountingMinutes(str) {

// code goes here

// Declare variables for calculating difference in minutes

// variables in JavaScript are declared with "let" keyword

/* Build regelar expression which will match the pattern of "12houttime-12hourtime"

and extract time or hours in numbers from it */

let extractedTimeStringArray = str.match(/(\d+)\:(\d+)(\w+)-(\d+)\:(\d+)(\w+)/);

// extractedTimeStringArray array will be like- ["1:00pm-11:00am", "1", "00", "pm", "11", "00", "am", index: 0, input: "1:00pm-11:00am", groups: undefined] for str = "1:00pm-11:00am"

// console.log('object', time)

// Extract array value at 1st index for getting first time's hours (ie time before hyphen like 1:00pm in 1:00pm-11:00am ) (like 11 from 11:32am) and convert them to minutes by multiplying by 60

let mintsOfFirstTimeFromHours = extractedTimeStringArray[1] * 60;

// Extract array value at 2nd index for getting first time's minutes like 32 from 11:32am

let mintsOfFirstTimeFromMints = extractedTimeStringArray[2];

// Extract array value at 4th index for getting second time's hours (ie time after hyphen like 11:00am in 1:00pm-11:00am ) and convert them to minutes by multiplying by 60

let mintsOfSecondTimeFromHours = extractedTimeStringArray[4] * 60;

// Extract array value at 5th index for getting second time's minutes like 32 from 11:32am

let mintsOfSecondTimeFromMints = extractedTimeStringArray[5];

// if second time's 12 hour time is in pm

if (extractedTimeStringArray[6] === "pm") {

// Add 12 * 60 = 720 minutes for 12 hrs

mintsOfSecondTimeFromHours += 720;

}

// if first time's 12 hour time is in pm

if (extractedTimeStringArray[3] === "pm") {

// Add 12 * 60 = 720 minutes for 12 hrs to first time

mintsOfFirstTimeFromHours += 720;

// Add 12 * 60 *2 = 1440 minutes for 24 hrs to second time

mintsOfSecondTimeFromHours += 1440;

}

// Calculate output minutes difference between two times separated by hyphen

str = (mintsOfSecondTimeFromHours - mintsOfFirstTimeFromHours) + (mintsOfSecondTimeFromMints - mintsOfFirstTimeFromMints);

// return calculated minutes difference

return str;

}

// keep this function call here

// call the function and console log the result

console.log(CountingMinutes("1:00pm-11:00am"));

// output in console will be- 1320

A SOHO's connection to the internet is through an antenna that sends and receives a microwave signal to the ISP's antenna. There

aksik [14]

Answer:

Line of sight wireless

Explanation:

Line of sight wireless are wireless which enable antenna to sends and receives a microwave signal to the ISP's antenna

By standing between the mounted antenna at client building so that the other side of the wireless connection you intend to create can be visible.

Line of Sight wireless also provide electro-magnetic radio waves that tends to be less affected by external forces leading to better connection reliability because all wireless networks excel only with true line of sight that is why it is always advisable that the antennas are mounted above the tree line, to ensure proper connections without obstacles between them since

Line of sight depend on having a clear line of sight between the antenna and the hotspot .
