OuterItem:2 InnerItem:1 OuterItem:3 InnerItem:1 内部循环在外部循环反复执行过程中只执行一遍,这是因为break语句在每次执行第1个Write-Host语句后终止循环。如果要终止外部循环,而不是内部循环,则可以在外部循环中增加break语句; PS C:\>:OuterLoop foreach ($outerItem in 1..3){ >> Write-Host "OuterI...

如果条件 $innerCounter -le 3（小于或等于 3）保持为 true，则内部循环将继续。对于每次内循环迭代，我们都会显示“Inner Loop Iteration: $innerCounter”。内部循环完成后，我们将 $outerCounter 加 1 并开始外部循环的下一次迭代。外部循环继续，直到 $outerCounter 不再小于或等于 3。执行时，该脚本将产生以下...
The break statement in PowerShell is used to terminate the loop. When the break statement is executed inside the inner loop, it terminates that loop execution, and when it is placed in the outer loop, it terminates the entire loop, including child loop(s). The break statement is used with...

measure for execution time for any program). For any nested for loop time complexity is O(n^2). A nested loop is a “for loop” within a “for loop” or an inner loop will be the statement for the outer loop. We can put a break in any inner or outer loop to halt the loop. ...
An important point to be aware of when breaking out of a nested for loop is that the break only exits from the current level of loop. For example, the following Windows PowerShell example will exit from the current iteration of the nested loop when j is equal to 5. The outer loop will...
