You can code something like:
Code:
SEQ=200
awk -v S="$SEQ" '
        {
                A[++c] = $1
        }
        END {
                for ( i = 1; i <= c; i++ )
                {
                        if ( A[i] == S )
                        {
                                C[A[i],A[i+1],A[i-1]]++
                                V[A[i],A[i+1],A[i-1]] = "the letter is " A[i] RS "followed by " A[i+1] RS "comes after " A[i-1]
                        }
                }
                for ( k in V )
                {
                        print C[k] " times"
                        print V[k]
                }
        }
' file

By default, the order in which a for (i in array) loop scans an array is not defined; it is generally based upon the internal implementation of arrays inside awk.

So you have to use an Indexed Array to help preserve the order, try this modified code:
Code:
SEQ=200
awk -v S="$SEQ" '
        {
                A[++c] = $1
        }
        END {
                for ( i = 1; i <= c; i++ )
                {
                        if ( A[i] == S )
                        {
                                if ( !(V[A[i] A[i+1] A[i-1]]) )
                                        T[++j] = A[i] A[i+1] A[i-1]
                                C[A[i] A[i+1] A[i-1]]++
                                V[A[i] A[i+1] A[i-1]] = "the letter is " A[i] RS "followed by " A[i+1] RS "comes after " A[i-1]
                        }
                }
                for ( i = 1; i <= j; i++ )
                {
                        print C[T[i]] " times"
                        print V[T[i]]
                }
        }

The result wasn't ordered descending based on times

Code:
 
25 times
the letter is 200
followed by 202
comes after 211
36 times
the letter is 200
followed by 223
comes after 212

it should print the 36 times result followed by 25 result

Thanks

I'm sorry. I misread your requirement. I thought you want to print records in the order that you have them in your input file.

If you have gawk then you can use below code to print in descending order:
Code:
SEQ=200
gawk -v S="$SEQ" '
        {
                A[++c] = $1
        }
        END {
                for ( i = 1; i <= c; i++ )
                {
                        if ( A[i] == S )
                        {
                                C[A[i],A[i+1],A[i-1]]++
                                V[A[i],A[i+1],A[i-1]] = "the letter is " A[i] RS "followed by " A[i+1] RS "comes after " A[i-1]
                        }
                }
                for ( k in V )
                {
                        T[++j] = C[k]
                }
                n = asort(T)
                for ( i = n; i >= 1; i-- )
                {
                        for ( k in V )
                        {
                                if ( C[k] == T[i] )
                                {
                                        print C[k] " times"
                                        print V[k]
                                }
                        }
                }
        }

Thanks Yoda
Suppose that I have texts in different languages

how I could print the frequent n words

like frequent 10 or 100 ?

It is easy to do it for A-Z which is English

but, regardless the input language text how I can do it?



Thanks
