Get counts from List
This is very easy , but I`m struggling .. please help modify my script,

I want to count the number of h and n , from the second column group by the first. The second column is binary, can only have h and n.


Code:
a	h
a	h
a	n
a	n
a	h
b	h
b	h
b	h
b	h
b	h
c	n
c	h
c	h
c	h
c	h

Desired output

Code:
	h	n
a	3	2
b	5	0
c	4	1


My try

Code:
awk  '{A[$1]+=$2}END{for (i in A) print i,A[i]}' file

Like so:
Code:
awk     '       {LN[$1]; HD[$2]; MX[$1,$2]++}
         END    {               printf "%10s", ""; for (i in HD) printf "%10s", i; print "";
                 for (j in LN) {printf "%10s",j;   for (i in HD) printf "%10s", MX[j,i]+0; print ""}
                }
        ' file
                   h         n
         a         3         2
         b         5         0
         c         4         1
