Algorithm Analysis

Increase the number $n$ by 1. Next, in a loop while $n$ is not divisible by 10, we will increase $n$ by 1. As soon as the number $n$ is divisible by 10, it is the answer.

Algorithm Implementation

Read the input number $n$.

scanf("%d", &n);

Increase the number $n$ by 1.

n++;

While $n$ is not divisible by 10, increase $n$ by 1.

while (n % 10 != 0) n++;

Output the answer.

printf("%d\n", n);
