## 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 = [[0]*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
