Búsqueda lineal en Python

En esta publicación de Python, aprenderá lo siguiente:

  • ¿Qué es una búsqueda lineal?
  • Algoritmo de búsqueda lineal
  • Escriba un programa Python para búsqueda lineal usando While Loop
  • Escriba un programa Python para búsqueda lineal usando For Loop
  • Búsqueda lineal en el programa Python usando recursividad

¿Qué es una búsqueda lineal?

En primer lugar, una búsqueda lineal, también conocida como búsqueda secuencial, este método se utiliza para encontrar un elemento dentro de una lista o matriz. Comprueba cada elemento de la lista uno por uno / secuencialmente hasta que se encuentra una coincidencia o se ha buscado en toda la lista.

Algoritmo de búsqueda lineal

Implemente la búsqueda lineal siguiendo los pasos a continuación:

  • Recorre la lista / matriz usando un bucle.
  • En cada iteración, asocie el  target valor con el valor dado de la lista / matriz.
    • Si los valores coinciden, devuelve el índice actual de la lista / matriz.
    • De lo contrario, continúe con el siguiente elemento de matriz / lista.
  • Si no se encuentra ninguna coincidencia, regrese  -1.

Escriba un programa Python para búsqueda lineal usando While Loop

# python program for linear search using while loop

#define list
lst = []

#take input list size
num = int(input("Enter size of list :- "))

for n in range(num):
    #append element in list/array
    numbers = int(input("Enter the array of %d element :- " %n))
    lst.append(numbers)

#take input number to be find in list   
x = int(input("Enter number to search in list :- "))

i = 0
flag = False

while i < len(lst):
	if lst[i] == x:
		flag = True
		break

	i = i + 1

if flag == 1:
	print('{} was found at index {}.'.format(x, i))
else:
	print('{} was not found.'.format(x))

Después de ejecutar el programa, la salida será:

Enter size of list :-  5
Enter the array of 0 element :-  10
Enter the array of 1 element :-  23
Enter the array of 2 element :-  56
Enter the array of 3 element :-  89
Enter the array of 4 element :-  200

Recherche linéaire en Python

Dans cet article Python, vous apprendrez ce qui suit :

  • Qu'est-ce qu'une recherche linéaire ?
  • Algorithme de recherche linéaire
  • Écrire un programme Python pour la recherche linéaire à l'aide de la boucle While
  • Écrire un programme Python pour la recherche linéaire à l'aide de la boucle For
  • Recherche linéaire dans le programme Python à l'aide de la récursion

Qu'est-ce qu'une recherche linéaire ?

Tout d'abord, une recherche linéaire, également appelée recherche séquentielle, cette méthode est utilisée pour rechercher un élément dans une liste ou un tableau. Il vérifie chaque élément de la liste un par un / séquentiellement jusqu'à ce qu'une correspondance soit trouvée ou que toute la liste ait été recherchée.

Algorithme de recherche linéaire

Implémentez la recherche linéaire en suivant les étapes ci-dessous :

  • Parcourez la liste/le tableau à l'aide d'une boucle.
  • À chaque itération, associez la  target valeur à la valeur donnée de la liste/du tableau.
    • Si les valeurs correspondent, renvoie l'index actuel de la liste/du tableau.
    • Sinon, passez à l'élément de tableau/liste suivant.
  • Si aucune correspondance n'est trouvée, retournez  -1.

Écrire un programme Python pour la recherche linéaire à l'aide de la boucle While

# python program for linear search using while loop

#define list
lst = []

#take input list size
num = int(input("Enter size of list :- "))

for n in range(num):
    #append element in list/array
    numbers = int(input("Enter the array of %d element :- " %n))
    lst.append(numbers)

#take input number to be find in list   
x = int(input("Enter number to search in list :- "))

i = 0
flag = False

while i < len(lst):
	if lst[i] == x:
		flag = True
		break

	i = i + 1

if flag == 1:
	print('{} was found at index {}.'.format(x, i))
else:
	print('{} was not found.'.format(x))

Tìm kiếm tuyến tính bằng Python

Trong bài đăng python này, bạn sẽ tìm hiểu những điều sau:

  • Tìm kiếm tuyến tính là gì?
  • Thuật toán tìm kiếm tuyến tính
  • Viết chương trình Python để tìm kiếm tuyến tính bằng While Loop
  • Viết chương trình Python để tìm kiếm tuyến tính bằng For Loop
  • Tìm kiếm tuyến tính trong Chương trình Python sử dụng Đệ quy

Tìm kiếm tuyến tính là gì?

Trước hết, Tìm kiếm tuyến tính, còn được gọi là tìm kiếm tuần tự, phương pháp này được sử dụng để tìm một phần tử trong danh sách hoặc mảng. Nó kiểm tra từng phần tử của danh sách một / tuần tự cho đến khi tìm thấy một kết quả phù hợp hoặc toàn bộ danh sách đã được tìm kiếm.

Thuật toán tìm kiếm tuyến tính

Triển khai tìm kiếm tuyến tính theo các bước sau:

  • Duyệt qua danh sách / mảng bằng cách sử dụng một vòng lặp.
  • Trong mỗi lần lặp, hãy liên kết  target giá trị với giá trị đã cho của danh sách / mảng.
    • Nếu các giá trị khớp, trả về chỉ mục hiện tại của danh sách / mảng.
    • Nếu không, hãy chuyển sang phần tử mảng / danh sách tiếp theo.
  • Nếu không tìm thấy kết quả phù hợp, hãy quay lại  -1.

Viết chương trình Python để tìm kiếm tuyến tính bằng While Loop

# python program for linear search using while loop

#define list
lst = []

#take input list size
num = int(input("Enter size of list :- "))

for n in range(num):

    lst.append(numbers)

#take input number to be find in list   
x = int(input("Enter number to search in list :- "))

		break

	i = i + 1

if flag == 1:
	print('{} was found at index {}.'.format(x, i))
else:
	print('{} was not found.'.format(x))

Lineare Suche in Python

  • Was ist eine lineare Suche?
  • Linearer Suchalgorithmus
  • Schreiben Sie ein Python-Programm für die lineare Suche mit While-Schleife
  • Schreiben Sie ein Python-Programm für die lineare Suche mit der For-Schleife
  • Lineare Suche im Python-Programm mit Rekursion

Was ist eine lineare Suche?

Eine lineare Suche, auch bekannt als sequentielle Suche, diese Methode wird verwendet, um ein Element innerhalb einer Liste oder eines Arrays zu finden. Es überprüft jedes Element der Liste nacheinander / sequentiell, bis eine Übereinstimmung gefunden wird oder die gesamte Liste durchsucht wurde.

Linearer Suchalgorithmus

Implementieren Sie die lineare Suche mit den folgenden Schritten:

  • Durchlaufen Sie die Liste/das Array mit einer Schleife.
  • Verknüpfen Sie in jeder Iteration den  target Wert mit dem angegebenen Wert der Liste/des Arrays.
    • Wenn die Werte übereinstimmen, geben Sie den aktuellen Index der Liste/des Arrays zurück.
    • Fahren Sie andernfalls mit dem nächsten Array-/Listenelement fort.
  • Wenn keine Übereinstimmung gefunden wird, geben Sie zurück  -1.

# python program for linear search using while loop

O que é uma pesquisa linear?

Em primeiro lugar, uma pesquisa linear, também conhecida como pesquisa sequencial, este método é usado para localizar um elemento dentro de uma lista ou array. Ele verifica cada elemento da lista um por um / sequencialmente até que uma correspondência seja encontrada ou toda a lista tenha sido pesquisada.

Algoritmo de pesquisa linear

Implemente a pesquisa linear seguindo as etapas abaixo:

  • Percorra a lista / array usando um loop.
  • Em cada iteração, associe o target valor ao  valor fornecido da lista / matriz.
    • Se os valores corresponderem, retorne o índice atual da lista / matriz.
    • Caso contrário, vá para o próximo elemento de array / lista.
  • Se nenhuma correspondência for encontrada, retorne  -1.

Escreva um programa Python para pesquisa linear usando loop while

# python program for linear search using while loop

#define list
lst = []

#take input list size
num = int(input("Enter size of list :- "))

for n in range(num):
    #append element in list/array
    numbers = int(input("Enter the array of %d element :- " %n))
    lst.append(numbers)

#take input number to be find in list
