Answer 1

% idea is to check each pair in the list of pair and swap the character for

% those two indexes

function s = suffletext(pair, s)

i = 1;

while i <= size(pair, 1)

%exract the two index from pair

temp = pair(i, :);

% swap the two characters

t = s(temp(1));

s(temp(1)) = s(temp(2));

s(temp(2)) = t;

i = i + 1;

end

end
