For a positive integer n$,$ what is the value of the counter after the fol$-$ lowing code has been executed. $($Both C and Python code are included, use the language you are familiar with.$)$

C code:

int i$,$j$,$k$,$counter;

counter $=0$;

for$($ i$=1$; i$<=$n; i$++)$

python code:

counter $=0$

for i in range$(1,$n$+1)$:

for j in range$(1,$i$+1)$:

for$($ j$=1$; j$<=$i; j$++)$ for k in range$(1,$j$+1)$:

for$($ k$=1$; k$<=$j; k$++)$ counter $=$ counter $+1$

counter $++$;
