code is in python but u can apply the logic in any other coding language as well.

def somefn(s):
         a=len(s)
         s1=''
         for i in range(a):
                    if i!=a-1:
                               s1=s1+s[i][0]
                    else:
                               s1=s1+s[i][0]+s[i][2]
           return s1
