Balanced Paranthesis

-
For a given a string expression containing only round brackets or parentheses, check if they are balanced or not. Brackets are said to be balanced if the bracket which opens last, closes first. Example: Expression: (()()) Since all the opening brackets have their corresponding closing brackets, we say it is balanced and hence the output will be, 'true'. You need to return a boolean value indicating whether the expression is balanced or not. Note: The input expression will not contain spaces in between. Input Format: The first and the only line of input contains a string expression without any spaces in between.  Output Format: The only line of output prints 'true' or 'false'. Note: You don't have to print anything explicitly. It has been taken care of. Just implement the function. Constraints: 1 <= N <= 10^7 Where N is the length of the expression. Time Limit: 1sec Sample Input 1 : (()()()) Sample Output 1 : true Sample Input 2 : ()()(() Sample Outp...

How to trigger "Scan Multibranch Pipeline Now"

-
Image
 Hey everyone 😀, Sometimes developers face a common issue related to trigger a job using the Jenkins pipeline. As we all know to trigger Freestyle Job using pipeline  we write code something similar which is mention below build JOB_NAME; but what if we want to trigger a multi-branch job or trigger   Scan Multibranch Pipeline Now. If we try to trigger a multibranch job by using the above code  it gives an error, something similar like  ERROR: Waiting for non-job items is not supported As we see it doesn't work, the reason is that it is a non-wait type job item, so the only thing we need to do is to add a wait=false statement in the code. I know it's not so big thing but sometimes people missed this little thing. Hope you enjoyed my blog post.😎
