# Array challenge 1
### pseudocode
- precompute the sum of the array.
- use reduce to get sum
- get the 2 maximum values from the array
- compare product of the 2 maximum and precomputed sum and return true if product is greater than the precomputed sum

### solution

function ArrayChallenge(arr) {
  if (arr.length < 2) return 'false';

  // init two max - numbers
  let maxNeg = 0;
  let neg = 0;

  //   init two max + numbers
  let pos = 0;
  let maxPos = 0;

  const sum = arr.reduce((total, num) => {
    // Get the two max negative numbers
    if (num < 0) {
      if (num < neg) maxNeg = num;
      else neg = num;
    }
    // Get the two max positive numbers
    else {
      if (num >= maxPos) {
        pos = maxPos;
        maxPos = num;
      } else if (num > pos) pos = num;
    }

    //   Get total / sum
    return total + num;
  }, 0);

  //   check required condition ? "true" : "false"
  if (maxPos * pos > sum * 2 || maxNeg * neg > sum * 2) return 'true';
  else return 'false';
}

# Backend challenge
### PseudoCode

- Liten to incoming https response from the server
- Parse data / set encoding to readble chunks
- Map and match data for the required value and Get index of the corresponding key

    age=32

- Store the key to an array
- Write the string value of the array to a file called output.txt using an encoding not sure which?
- Listen to buffer response and update on shaSum

     crypto.createHash('sha1').update(fileData)   

- reverse the hex value of the hash and join to the reverse value of the given token
- return the string / reversed hash value

### solution

const https = require('https');
const fs = require('fs');
const crypto = require('crypto');

https.get('https://coderbyte.com/api/challenges/json/age-counting', (resp) => {
  let data = '';
  let reverseToken = '5ux7jfnrb6a1'.split('').reverse().join('');

  // set readable encoding
  resp.setEncoding('utf-8');

  //  incoming data
  resp.on('data', (d) => {
    data += [d];
  });

  resp.on('end', () => {
    // set array
    let parsedData = data.toString().split(',');

    // copy array
    let arr2 = parsedData;

    // array to store key for data matching age=32
    let arr3 = [];

    // crypto initialize
    let algorithm = 'sha1';
    let shaSum = crypto.createHash(algorithm);

    // match and use index to  key
    parsedData.map((data, index) => {
      let t = data.match('age=32');
        if (t) {
          arr3.push(arr2[index - 1].split(' ')[1]);
        }
    });

    arr3.push('\n');

    // use fs.createWriteStream() method
    // To write the file
    try {
      const writeStream = fs.createWriteStream('output.txt', { flags: 'w' });

      writeStream.write(arr3.join(','), (err) => {
        if (err) {
          throw err;
        }

        // initialize read stream
        const reader = fs.createReadStream('output.txt');

        // encrypt buffer output and return reverse
        // hex value of encryption + reverse token on end
        reader.on('data', (chunk) => {
          shaSum.update(chunk.toString());
        });
        reader.on('end', () => {
          let hash = shaSum.digest('hex');
          console.log(hash.split('').reverse().join('') + ':' + reverseToken);
        });
      });
    } catch (e) {
      throw e;
    }
  });
  resp.on('error', (e) => {
    console.error(e);
  });
});

# Array challenge 3

### brake down
- Imagine the array as a graph of n nodes, and an edge directed from node `i` to node `j` and the element at the `i'th` index muxt be present at the `j'th` index in the sorted array
- The graph will now have many non-intersecting cycles

example array `[4, 3, 2, 1]`

const cycle_1 = [1,3,2,4]
const cycle_2 = [1,2,3,4]


### pseudocode
- Create two items in array and use as pairs where the first item is the element itself and second item is position of the element using a for loop
- Sort the array to track right position of every element. This is through the array method `sort`
- To keep track of visited elements. Initialize all elements as not visited or false using a for loop
- Then initialize result

let ans = 0

- Traverse array elements using a for loop. If already swapped and corrected or already present at correct position, continue
- Then find out the number of node in this cycle and add in results and While not visited move to next node
- Update answer by adding current cycle
- return result

### solution

function minSwaps(arr) {
  let n = arr.length;

  // Create two items and use as pairs where first item is the element
  // and second item is position of element

  let arrpos = [];
  for (let i = 0; i < n; i++) arrpos.push([arr[i], i]);

  // Sort the array  to get right position of every element

  arrpos.sort(function (a, b) {
    return a[0] - b[0];
  });

  // To keep track of visited elements.
  // Initialize a new array with n nodes
  // Then initialize all elements as not visited or false.

  let vis = new Array(n);
  for (let i = 0; i < n; i++) {
    vis[i] = false;
  }

  // Initialize result
  let ans = 0;

  // Traverse array elements
  for (let i = 0; i < n; i++) {
    // already swapped and corrected or already present 
    // at correct position continue

    if (vis[i] || arrpos[i][1] == i) continue;

    // find out the number of node in this cycle and add in ans

    let cycle_size = 0;
    let j = i;
    while (!vis[j]) {
      vis[j] = true;

      // move to next node

      j = arrpos[j][1];

      cycle_size++;
    }

    // Update answer by adding current cycle.
    if (cycle_size > 0) {
      ans += cycle_size - 1;
    }
  }

  // Return result
  return ans;
