Algorithm and Flowchart to find the smallest element in an array

[11096 views]


An array is a data structure containing elements of the same data type. These elements are stored in contiguous locations in the memory.

Hence, we can easily find out the position of each element of the array by adding the base address with an offset value. Offset is the difference between two indexes of the array and the base address is the memory location of the first element of the array.

The elements of an array can be accessed through the it’s index. For example if we want to access the second element of an array, we can write: a[1]. Here the index the required variable in the array ‘a’ is 1.

Note: The index of an array always starts with 0.

Arrays are very important data structures since arrays are used to implement other data structures like stack, queue, linked-list, heaps, etc. Arrays have a very wide range of implementation. In this article, we will see the simplest approach to find out the smallest or minimum element in a given array.

Algorithm to find out the Smallest Element in an array:

Step 1: Start Step 2: Read the size of the array from the user, say ‘n’ Step 3: Declare an array of size n, say a[n] Step 4: Initialize loop variable, i = 0 Step 5: Repeat while i < n: 5.1: Read the array element at position ‘i’ 5.2: Increment i by 1 Step 6: Initialize smallest element, min = a[0] Step 7: Initialize loop variable, i = 0 Step 8: Repeat while i < n: 8.1: If a[i] < min, then: 8.1.a: min = a[i] 8.2: Increment i by 1 Step 9: Print the smallest element, min Step 10: Stop

Explanation:

In this algorithm, we will first take the size of the array as input from the user. Then we will declare an array of the size given by the user. Now, to take the elements as input, we will start a loop. The loop variable is initialized as 0. Then the elements are taken as input one by one. Once this is done, we initialize the smallest element, min, as the first element of the array, that is, a[0]. Then another loop is started with initial value 0. In this loop, we will compare each element of the array with the variable min. If the element a[i] is less than min, then value of min is replaced with the value of a[i]. When all the iterations of the loop are over, we get the minimum element in the array, stored in the variable min.

How to find the minimum value in an array flowchart

Mathematics

Overview

In this post, we will create a flowchart to find the minimum value in an array. We will use the RAPTOR flowchart. We will keep track of the lowest value in an array using a tracking variable LowestValue. We will assign the first value of the array to this variable.

The first value in the array is :

array_variable[1]

For example marks[1]

To read values into an array, follow the link:

Draw a flow chart to find minimum element of given list

After the loop iteration, we will have the minimum array element in the tracking variable. We can use the output symbol to print the lowest element.

Flowchart

Let’s create the flowchart to find the lowest element in the array: marks

FindMin is the RAPTOR procedure that takes the marks array as an input parameter. We can call this procedure using the Call symbol.

Draw a flow chart to find minimum element of given list

In a loop, we will check every element in the array if the element is lesser than this variable. If the array element is lesser than we store this array element in the tracking variable.

LowestValue <- marks[index]

If the array element is greater than the tracking variable then we already have the minimum value so far in the tracking variable.

Pseudocode

FUNCTION FindMin(marks) DECLARE index DECLARE LowestValue LowestValue = marks(1) index = 1 DO UNTIL index > 5 IF marks(index) < LowestValue THEN LowestValue = marks(index) ELSE END IF index = index + 1 LOOP OUTPUT "The lowest value in the array=" + LowestValue END FUNCTION

Common mistakes:

In the RAPTOR flowchart, the array index starts with 1 and not with zero. We can’t use marks[0] to denote the first element, unlike in other programming languages like C, Java etc.

can't use 0 as an array index

We know that Alice has 5 subjects. So the index starts with 1 and ends with 5. We can’t access the array with a higher number as the index. index of the array should be within the interval 1 and length_of(marks)

Flowchart to find largest element in an array in python

Develop a flowchart to find the largest element in an array in python. In this, we have to find the largest element which is entered by the user. we will also see max and min difference and max and min using def.

Aim to find max in list Python

In this program, we will learn to draw the flowchart for finding the largest element in the array.

Algorithm to find largest element in an array

  • Step-1: Start
  • Step-2: Enter the array size and read as n.
  • Step-3: Enter the array elements and read as a[i].
  • Step-4: Initialize to i and a[i] to large.
  • Step-5: In i loop check the condition i>n-1.
  • Step-6: check the condition a[i+1]>large
  • Step-7: If the condition is true then assign a[i+1] to large, otherwise go to next iteration.
  • Step-8: Print the largest element in an array in python
  • Step- 9: End
