Problem 59721. finding vector pair with min angle between them
given a matrix with more than one row , compare row vectors of the given matrix and find the pair with the minumum angle between them , "without using the dot fucntion"
you can find the angle from the following formula
θ = cos-1 [ (a. b) / (|a| |b|) ]
the product between the two vectors is the dot product
a⋅b=∑(ai)*(bi) from i=1 to n
the length of a vector is the square root of the sum of the squares of the components

The expected results for tests 2 and 4 seem to be incorrect.

I will be sure to check them and fix them if there are any problems

yep you are right I had a mistype in my code so it did not run on the whole matrix
