Lab $2$

Using $3$ threads, write a multithreaded program in Python to calculate the sum of non$-$negative

numbers from $0$ to $N.$

Sum $={\displaystyle \underset{i=1}{\overset{N}{}}}i$

How long does it take to run your code?

Example

Input

$N=11$

Output

start time $6957\mathrm{.}286042$ seconds$($s$)$

finish time $6957\mathrm{.}286906$ seconds$($s$)$

Finished in $0\mathrm{.}000864$ second$($s$)$

I am thread: $0$ this is my result $3_{{?}_{?}}$

I am thread: $1$ this is my result ${12}_{{?}_{?}}$

I am thread: $2$ this is my result $40$
