hi can you explain this psedu in details please

<-- means (Arrow)

Naive stack pseudo code :

Search(T,P)

n=text length //T

m=pattern length //P

Stack s

loop i <-- 0 until i<=n-m

loop j <-- j < m

if P[j]~=T[i+j]

break

if j=m

add i to s

print (size of s)

c[] <-- s toArray

loop k <-- 0 k< size of c

print c of k

END
