Python Program for Replace All 0’s With 1 In A Given Integer
Replace All 0’s With 1 In A Given Integer using Python
Here we will discuss how to Replace All 0’s With 1 In A Given Integer using Python.
The concept is simple, find the digits of the integer. Compare each digit with 0 if the digit is equal to 0 then replace it with 1. Construct the new integer with the replaced digits.
Implementation
- We will convert the integer into string.
- Then we will convert it into list and then we will traverse through the list.
- Wherever we find a ‘0’ we will replace with ‘1’.
Question can come like Way 1
Write a code to change all zero's as one's (0s as 1s) in a given number? ex: 120014 needs to be printed as 121114
Question can come like Way 2
implement a c program to replace all 0's with 1 in a given integer as an input, all the 0's in the number has to be replaced with 1.
Algorithm
- Take Input in num and initialize a variable num with with value 0
- If num is equals to zero then update the value of num2 to 1
- Iterate using a while loop until num is greater then 0
- For each iteration initialize a variable rem and store unit digit of num
- If rem equals to 0 then set rem to 1
- Set num to num divide by 10 & num2 equals to num2*10+rem
- Reverse and print num2
Method 1
Run
num = int(input("Enter number : "))
num2 = 0
if num == 0:
num2 = 1
while num > 0:
rem = num % 10
if rem == 0:
rem = 1
num = num//10
num2 = num2 * 10 + rem
num = 0
while num2 > 0:
r = num2 % 10
num = num * 10 + r
num2 //= 10
print("Converted number is:", num)
Method 2
Run
#taking Input
n=int(input('Enter number: '))
#converting into string
n=str(n)
#then into the list
n=list(n)
r="" #empty string for addind it the item of list
for i in range(len(n)):
#if we find '0' we will replace it with '1'
if(n[i]=='0'):
n[i]='1'
r=r + n[i] #creating the new integer
del n
print("Converted number is :",int(r))
Method 3
Run
n=int(input("Enter number: "))
s=str(n)
l=[]
for i in s:
if(i=='0'):
l.append('1')
else:
l.append(i)
ns=""
for i in l:
ns+=i
print("Converted number is:", int(ns))
Method 4
Run
#take inputs
Val = int(input('Enter number:'))
#change type to string
Val = str(Val)
Replaced = Val.replace('0','1')
print("Converted number is:" + Replaced)
Output
Enter number: 12090 Converted number is: 12191
