CA 06 - Find the Maximum and Minimum Element in the Array

 Min and Max in Array

Given an array arr[]. Your task is to find the minimum and maximum elements in the array. 
Input: arr[] = [1, 4, 3, 5, 8, 6]
Output: [1, 8]
Explanation: minimum and maximum elements of array are 1 and 8.
Input: arr[] = [12, 3, 15, 7, 9]
Output: [3, 15]
Explanation: minimum and maximum element of array are 3 and 15.

CODE:

    The first element of the array is appointed as the min and max value. Then the whole list is traversed and each element is checked with the current min and max element, if it is otherwise then the new min or max element is set to the current element. Here the first value need not be checked, but avoiding it is trivial and does not affect much hence we leave it as such.

Time Complexity: O(n)

class Solution:
    def getMinMax(self, arr):
        minarr = arr[0]
        maxarr = arr[0]
        for i in arr:
            if i > maxarr:
                maxarr = i
            elif i<minarr:
                minarr = i
        return [minarr,maxarr]

CA 04 - Two Sum & Sorted Two Sum

Image
  MY CODE: In brute force method the intuitive way of solving this problem with two for loop. Using nested loop to traverse through the list and try different combination of two sum to check if it matches with the target.    Time complexity: O(n^2)       OPTIMIZED:          In the optimized method of approaching the Two Sum problem. The given list is already sorted in ascending order. This gives us the leverage of using Two pointer technique to solve this problem. Thus using single loop to approach this problem. If current sum is less than target move the left pointer, if it is greater move the right pointer else return the current index (equal to target).  Time complexity: O(n) MY CODE:

CA 05 - Reverse the array

  Array Reverse Reverse an array  arr[] . Reversing an array means  rearranging  the elements such that the  first  element becomes the  last , the  second  element becomes  second last  and so on. Input: arr[] = [1, 4, 3, 2, 6, 5] Output: [5, 6, 2, 3, 4, 1] Explanation: The first element 1 moves to last position, the second element 4 moves to second-last and so on. Input: arr[] = [4, 5, 1, 2] Output: [2, 1, 5, 4] Explanation: The first element 4 moves to last position, the second element 5 moves to second last and so on. CODE:     BRUTE FORCE METHOD:          Here, in this method we will create a temporary array to store the reversed given array and then assign it to the given array class Solution :     def reverseArray ( arr ):         n = len (arr)         temp = [ 0 ] * n         for i in range (n- 1 ,- 1 ,- 1 ): ...

CA 21 - Basic Select SQL Queries

Image
 1.  Query all columns for a city in   CITY   with the   ID   1661 . The  CITY  table is described as follows: Here we make use of the where conditon cllause to retrieve the details of the Id with 1661, we select all the columns to be displayed and "*" is avoided for best practice. SOLUTION: SELECT ID,NAME,COUNTRYCODE,DISTRICT,POPULATION FROM CITY where ID = 1661 ; 2. Query all columns for all American cities in the   CITY   table with populations larger than   100000 . The   CountryCode   for America is   USA . The  CITY  table is described as follows: Here we make use of the where condtional clause, to obatin the population to be over thhe given number we make use of the' >' symbol to achieve this. Also the AND operator is used to state two where conditons where we want only the details of cities in USA so we use the countrycode check with 'USA' single quotes are used to check with the value, usage ...
