the system.linq.expressions.expressionvisitor has method named visitextension seems nothing other call visitchildren method on expression being visited. protected internal virtual expression visitextension(expression node) { return node.visitchildren(this); } i understand visitchildren does. understand virtual implementation can , perhaps meant overriden. gather documentation of method on msdn , sparing in words , briefly remarks: visits children of extension expression. can overridden visit or rewrite specific extension nodes. if not overridden, method call visitchildren, gives node chance walk children. default, visitchildren try reduce node. i not find explanation helpful. specifically, phrase jets me out of abilities of comprehension "or rewrite specific extension nodes." i understand rest of it, pertains reduction or breaking down of expression sub-expressions. also in same namespace enumeration named expressiontype , purpose of understand well. ...

i'd use function generate 2 arrays of same length values of first , second array shouldnt duplicates , neither values in first array shall not in second one. what i've tried far: function generatesiruri(width){ var exists = false; for(var = 0; < width; i++){ var randomnumber = math.floor(math.random()*101); var secondrandomnumber = math.floor(math.random()*101); if(sir1[i] == randomnumber && sir2[i] == secondrandomnumber && randomnumber == secondrandomnumber && sir1[i] == secondrandomnumber){ exists = true; return; } if(!exists){ sir1.push(randomnumber); sir2.push(secondrandomnumber); } } sortascending(sir1); sortascending(sir2); } function sortascending(array){ var sort; for(i = 0; < array.length; i++){ for(var j = 0; j < array.length; j++){...

the code bit messy, point divide different functions. i understand can test palindrome how use boolean variable, instead of stating straight away print function. def trial(): palindrome = true c = str(input("hey: ")) in range(len(c)): = c[i] s = c[-(i+1)] if (a == s): return break else: print ("no, not plaindrome") break return palindrom def output(): print true trial() output() you can use return value within function def ispalindrome(s): return s == s[::-1] def output(s): if ispalindrome(s): # use return value of above function print('it palindrome') else: print('not palindrome') for example >>> output('hello') not palindrome >>> output('abcba') palindrome

i have 3 different type of jobs running on data in hdfs. these 3 jobs have run separately in current scenario. now, we want run 3 jobs piping output data of 1 job other job without writing data in hdfs improve architecture , overall performance. any suggestions welcome scenario. ps : oozie not fitting workflow.cascading framework ruled out because of scalability issues. thanks hadoop inherently writes storage (e.g. hdfs) after m/r steps. if want in memory, maybe need spark.

can make 2 values in cell sortable? i need in same cell. possible write such. "value1"; "value2" or value1 | value2? i want list be: a b c d e f ... and not ab c d e f ... see picture. i believe excel treats data in cell 1 data. not recognize whitespace separation of data. your best bet split , b 2 cells vertically merge cells right, column-by-column. example
