第二个运行结果不对把

结果x也没有变。
而且用T当TRUE是非常坏的用法。
TRUE and FALSE are reserved words denoting logical constants in the R
language, whereas T and F are global variables whose initial values set to
these.

这个问题的b)问
R language if(), while() etc
A positive integer number n is a prime number if it is only divisible
by 1 and itself.
a)Use it to write checkDiv <- function(n,k) {........} which either
writes " is divisible by " or " / has remainer
" when it is not divisible. Hint: use paste()
b) Now use a loop, searching for possible divisors of n to write a function
is.primeNum <- function(n) { .... } which returns true whenever n is a prime
number.

Will Washington Kill Us All? — Paul Craig Roberts http://www.paulcraigroberts.org/2015/04/15/will-washington-kill
Did you know that Washington keeps 450 nuclear ICBMs on “hair-trigger alert
”? Washington thinks that this makes us “safe.” The reasoning, if it can
be called reason, is that by being able to launch in a few minutes, no one
will try to attack the US with nuclear weapons. US missiles are able to get
on their way before the enemy’s missiles can reach the US to destroy ours.

find out if there exist a row i and column j such that

2) all elements of column j are 1s

my thinking is:
sum each row and each column
if sumRow[i] > 1 mark it false
if sumCol[i]
also for those rows and cols,if they are not marked false, record the 1 posi
