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 = [[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
