Python Program to find Number Combination

You are Here:

Find Number Combination

In the following example, we will find all possible combinations of numbers with 4 and 8 within the limit 500.

Example

Python Compiler
import math combination = 2 num = [4, 8] limit = 500 print("List of combinations of 4 and 8 upto 500:"); #iterate from 1 to limit for i in range(1, limit+1): copyNum = i count = 0 flag = 0 #check each digit starting from last digit while(copyNum != 0): count += 1 lastDigit = copyNum % 10 for j in range(0, combination): if(num[j] == lastDigit): flag += 1 copyNum = math.floor(copyNum / 10) if(count == flag): print(i, end=" ")

Output

List of combinations of 4 and 8 upto 500: 4 8 44 48 84 88 444 448 484 488

Find Number Combination for any Given Numbers

In the following example, we will find all possible combinations of the given numbers within the given limit.

Example

Python Compiler
import math combination = int(input("Enter the number of Combination: ")) num = [*50 for _ in range(50)] for i in range(0, combination): num[i] = int(input("Enter (int) Digit %d: " % (i+1))) limit = int(input("Enter the limit: ")) #iterate from 1 to limit for i in range(1, limit+1): copyNum = i count = 0 flag = 0 #check each digit starting from last digit while(copyNum != 0): count += 1 lastDigit = copyNum % 10 for j in range(0, combination): if(num[j] == lastDigit): flag += 1 copyNum = math.floor(copyNum / 10) if(count == flag): print(i, end=" ")

Output

Enter the number of Combination: 2 Enter (int) Digit 1: 1 Enter (int) Digit 2: 2 Enter the limit: 500 1 2 11 12 21 22 111 112 121 122 211 212 221 222
