The program must accept an integer N as the input. The program must replace all the occurrences of the unit digit of N by 0 in the integer N. Finally, the program must print the modified value of N as the output.
Boundary Condition(s):
1 <= N <= 10^8
Input Format:
The first line contains the value of N.
Output Format:
The first line contains the modified value of N.
Example Input/Output 1:
Input
1021
Ouput
20
Explanation:
The unit digit of 1021 is 1.
So after replacing all the occurrence of 1 by 0, the integer becomes 0020.
Hence the output is 20
Example Input/Output 2:
Input
202202
Ouput
0
#include<stdio.h>
#include<stdlib.h>
int main()
{
int n;
scanf("%d",&n);
int k=0;
int a[10000000];
int m=n%10;
while(n>0)
{
if(n%10==m)
a[k]=n%10;
else
a[k]=0;
k++;
n/=10;
}
k--;
while(a[k]==0 && k>0)
{
k--;
}
for(;k>=0;k--)
{
printf("%d",a[k]);
}
}
