how to solve this problem?

Question

we input word in 7 variable string in one line.
if the input make the word "belalang", output="yes" else "no"
example input 1:
la be la ng be la ng
output 1:
yes
input 2:
la be la ng be la la
output 2:
no

Answer 1

Basically you can add a cursor and proceed if you found a matching character by traverse the 7 variable string.

If the cursor reach the end of the string you'll output yes. Here's a simulation:-

➡belalang
[l]a be la ng be la ng

➡belalang
l[a] be la ng be la ng

b➡elalang
la [b]e la ng be la ng

be➡lalang
la b[e] la ng be la ng

bel➡alang
la be [l]a ng be la ng

bela➡lang
la be l[a] ng be la ng

bela➡lang
la be la [n]g be la ng

bela➡lang
la be la n[g] be la ng

bela➡lang
la be la ng [b]e la ng

bela➡lang
la be la ng b[e] la ng

belal➡ang
la be la ng be [l]a ng

belala➡ng
la be la ng be l[a] ng

belalan➡g
la be la ng be la [n]g

belalang➡
la be la ng be la n[g]
