In Julia, the keyword until is used in conjunction with a loop. The until keyword specifies a condition for exiting the loop. The loop will continue running until the condition specified after until is true. Here is the general syntax for using until in a loop:
while
# code to execute while the condition is true
end
# or
repeat
# code to execute until the condition is true
until
Here is an example of a while loop with an until condition:
i = 1
while i <= 10
println(i)
i += 1
end
# Output:
# 1
# 2
# 3
# 4
# 5
# 6
# 7
# 8
# 9
# 10
In this example, the while loop will keep running until i is greater than 10. Once i equals 11, the loop will exit.
Here is an example of a repeat-until loop with an until condition:
i = 1
j = 0
repeat
j += i
i += 1
until i > 10
println(j)
# Output: 55
In this example, the repeat-until loop adds up all the values of i from 1 to 10 and stores the result in j. The loop stops once i is greater than 10.
