Diberikan sebuah string, kita perlu menemukan karakter berulang pertama dalam string, kita perlu menemukan karakter yang muncul lebih dari satu kali dan yang indeks kemunculan pertamanya paling sedikit dengan pemrograman Python Show
Jika tidak ada karakter yang berulang, cetak -1 Saya harap, Anda mengerti apa yang sebenarnya akan kami lakukan. Jadi mari kita lanjutkan… Metode kekerasanLintasi seluruh string dari awal hingga akhir Untuk setiap karakter periksa apakah berulang atau tidak Jika tidak ada pengulangan cetak karakter -1 Kompleksitas Waktu-O(N^2) str="codespeedy"
a=0
for i in range(0 , len(str) ): #traversing through the entire string
if a==1:
break
for j in range(i+1 , len(str)): #traversing characters after the current one
if str[i]==str[j]:
print(str[i])
a=1 #this character is the first repeating character
break
if a==0:
print(-1)
KELUARAN- d
Menggunakan Hashing -Dua lintasan stringGunakan kamus untuk menghitung berapa kali setiap karakter muncul dalam string – kuncinya adalah karakter dan nilainya adalah frekuensi
Pada traversal kedua, untuk setiap karakter periksa apakah berulang atau tidak dengan mencentang dict[str[i]] Jika kami menemukan karakter berulang pertama, kami keluar dari loop Kompleksitas Waktu-O(N) Di bawah ini adalah kode Python yang mengimplementasikan metode ini untuk tugas kita str="codespeedy"
dict={}
n=len(str)
for i in range(0 , n):
if str[i] in dict:
dict[str[i]]+=1;
else:
dict[str[i]]=1
a=0
for i in range(0 , n):
if dict[str[i]]>1:
print(str[i])
a=1
break
if a==0:
print(-1)

Menggunakan Hashing -Satu traversal dari stringMulailah dengan menginisialisasi ans ke len(str)+1, yang akan digunakan untuk menyimpan indeks dari karakter berulang pertama Dalam kalimat tertentu mungkin ada kata yang diulang sebelum kalimat berakhir. Dalam program python ini, kita akan menangkap kata yang diulang dalam kalimat. Di bawah ini adalah langkah-langkah logis yang akan kita ikuti untuk mendapatkan hasil ini
Program - Temukan Kata yang DiulangiDalam program di bawah ini kami menggunakan metode penghitung dari paket koleksi untuk menghitung jumlah kata Satu string diberikan. Tugas kita adalah menemukan kata berulang pertama dalam string yang diberikan. Untuk mengimplementasikan masalah ini kami menggunakan Koleksi Python. Dari koleksi tersebut, kita bisa mendapatkan metode Counter() AlgoritmaRepeatedword(n) /* n is the string */ Step 1: first split given string separated by space into words. Step 2: now convert the list of words into a dictionary. Step 3: traverse list of words and check which the first word has frequency >1 Kode contoh# To Find the first repeated word in a string from collections
import Counter
def repeatedword(n):
# first split given string separated by space into words
w = n.split(' ')
con = Counter(w)
for key in w:
if con[key]>1:
print ("REPEATED WORD IS ::>",key)
return
# Driver program
if __name__ == "__main__":
n=input("Enter the String ::")

Silakan selesaikan pada "PRAKTEK" terlebih dahulu, sebelum beralih ke solusi Pendekatan Sederhana. Mulai iterasi dari belakang dan untuk setiap kata baru, simpan di unordered_map. Untuk setiap kata yang muncul lebih dari satu , perbarui ans menjadi kata itu, terakhir balik ans dan cetaklah Penerapan C++

Pemisahan pertama diberikan string yang dipisahkan oleh spasi Sekarang ubah daftar kata menjadi kamus menggunakan koleksi. Metode penghitung (iterator). Kamus berisi kata-kata sebagai kunci dan frekuensinya sebagai nilai Sekarang lintasi daftar kata lagi dan periksa kata mana yang memiliki frekuensi lebih besar dari 1 Bagaimana menemukan karakter berulang pertama dalam string yang diberikan dengan Python?Diberi sebuah string, temukan karakter berulang pertama di dalamnya. . Salin larik yang diberikan ke larik bantu temp[] Urutkan array temp menggunakan algoritma pengurutan waktu O(N log N). Pindai array input dari kiri ke kanan. Untuk setiap elemen, hitung kemunculannya dalam temp[] menggunakan pencarian biner Bagaimana Anda menemukan kata-kata berulang dalam sebuah string?Algoritma . Tentukan string Ubah string menjadi huruf kecil agar perbandingan tidak sensitif Pisahkan string menjadi kata-kata Dua loop akan digunakan untuk menemukan kata duplikat. . Jika ditemukan kecocokan, tambahkan hitungan dengan 1 dan atur duplikat kata ke '0' untuk menghindari penghitungan lagi Bagaimana cara menemukan kata pertama dari teks dengan Python?Gunakan str. split() dan pengindeksan daftar untuk mendapatkan kata pertama dalam string . Hubungi str. split() untuk membuat daftar semua kata dalam str yang dipisahkan oleh spasi atau karakter baris baru. |
