#Day99-Finding Perfect Squares in a vector -Matlab Cody
Task:
Given a vector of numbers, return true if one of the numbers is a square of one of the other numbers. Otherwise return false.
Example:
Input a = [2 3 4]
Output b is true
Output is true since 2^2 is 4 and both 2 and 4 appear on the list.
Note: This code can be done using the in-built command. But for the challenge, I am trying to avoid those.
Matlab Code:
function b = isItSquared(a)
for i=1:1:length(a)
for j=1:1:length(a)
if (a(i))^2==a(j)
tf(i,j)=1;
else
tf(i,j)=0;
end
end
end
if sum(sum(tf(:,:))>0)
b=1;
else
b=0;
end
end
Sample Input and Output
a = [6 10 12 14 101];
assert(isequal(isItSquared(a),false))
>> a = [6 10 12 14 36 101];
assert(isequal(isItSquared(a),true))
>> a = [1,2,3,1,4,9];
>> b=isItSquared(a)
b =
1
