Calculate initial velocity

Problem Statement

The first equation of motion is $"v=u+a**t"$ where,

v: final velocity in meters$/$second

u: initial velocity in meters$/$second

a: acceleration in meters$/$second ${?}^2$

t: time interval in second

You are given the final velocity, acceleration, and time interval. Find the initial velocity.

Input Format

The input consists of a single line:

The line contains three integers $v,a,$ and $t$ respectively.

Input will be read from the STDIN by the candidate

Output Format:

Print the initial velocity i$.$e$.u.$

The output will be matched to the candidate's output printed on the STDOUT

Constraints:

$1v{10}^6$

$1a{10}^3$

$1t{10}^3$

Example:

Input:

$111$

Output

$0$

Explanation:

By first equation of motion we have $u=v-a**t,$ Now $v=a=t=1$ hence $u=1-1**1=0.$

Sample input

$522$

Sample Output

$1$

Instructions :

Program should take input from standard input and print output to standard output.
