Date | Time | Table | Checkin Time | Bill Number ..| .. | 7/1/2018 **18:03:48** **6** **18:03:48** **4332** 7/1/2018 18:11:23 **6** **18:03:48** **4332** 7/1/2018 18:23:10 **6** **18:03:48** **4332** 7/1/2018 19:24:11 8 19:24:11 4333 7/1/2018 19:56:17 8 19:24:11 4333 7/1/2018 20:31:11 *6 20:31:11 4332*
I need to calculate Checkin Time which is 1st time of table number and bill number.
For example See one customer checkin at
table number 6
Bill number is
table number 6 and
Bill number 4332
chekin time will be 1st
So I applied the formula:
But the value changes at
6th row .
checkin time .
It should be
18:03:48 because the
6th row table number and bill number is same as 1st one.
So How do I make it possible, to calculate the
checkin time as per
1st time who have same
bill and table number , no matter which row .
Here is the excel file I have uploaded to Google drive.
Here is the screenshot.
Edit:- Formula by @jeeped work, But as the log is of 30 days
The data keeps repeating the other day too.
Can it be done by giving some
unique date value ?
@Jeeped's answer is spot on, here is an adjustment for the formula to work over multiple days that have the same table numbers and bill numbers:
=AGGREGATE(15, 7, ((A$2:A$13)+(B$2:B$13))/((C$2:C$13=C2)*(E$2:E$13=E2)*(A$2:A$13=A2)), 1)
All I did was add this extra conditional argument, that checks if the "Date" is the same:
get (pair) - C++ Reference, Type of the elements in the pair . Function parameters. pr: A pair object. Return value. A reference to a member Get Value of first Pair. Ask Question Asked 1 year, 4 months ago. Active 1 year, But the value changes at 6th row. It's giving 20:31:11 as checkin time.
If you don't have the newer MINIFS and MAXIFS, use AGGREGATE to achieve the same result.
=AGGREGATE(15, 7, ((A$2:A$7)+(B$2:B$7))/((C$2:C$7=C2)*(E$2:E$7=E2)), 1)
Format the result any way you want; as date and time, time only, etc.
Pair in C++ Standard Template Library (STL), Syntax : pair& operator= (const pair& pr); This Assigns pr as the new content for the pair object. The first value is assigned the first value of pr and the second value is assigned the second value of pr . Python | Get first N key:value pairs in given dictionary Given a dictionary, the task is to get N key:value pairs from given dictionary. This type of problem can be useful while some cases, like fetching first N values in web development.
You can make use of an array formula combining
MATCH to return the earliest time value that matches your conditions first. In cell D2, enter the following:
When returning, be sure to press
CONTROL+SHIFT+ENTER instead of just
ENTER to make sure the formula calculates correctly.
std::get(std::pair), This articles presents how to extract the first elements of each item in a collection of pairs (or the keys of a map) in C++. I was trying to get first and second element of pair when i am using pair as key in map.For better clarification please see code below.This is what i have tried #include <bits/stdc++.h> using
Sets of pairs in C++, Pair s support $m[$k] style syntax for getting values by key. Pair s also support Returns the first value in the current Pair; ->get(int $key): mixed. Returns the The Pair class can be found in the javafx.util package. The constructor of this class takes two arguments, a key and its corresponding value: Pair<Integer, String> pair = new Pair<>(1, "One"); Integer key = pair.getKey(); String value = pair.getValue(); This example illustrates a simple Integer to String mapping using the Pair concept.
std::pair, Returns the next index, value pair. If index is nil (the default), returns the first pair. When called with the last index of the table (or with an index of nil for an empty First example. KeyValuePair is not just for the birds. Here we use it in a List. We store pairs of values in a single List. Two Lists could be used, but that might complicate matters. Part 1: Here we initialize a List of pairs. Each pair has 2 types separated by a comma (string, int).
How to Retrieve the Firsts from a Collection of Pairs, Dict s look for key=>value pairs, and the key is compared using isequal . Return an array containing the first index in b for each value in a that is a member of b Methods provided by the javafx.util.Pair class. Pair (K key, V value) : Creates a new pair. boolean equals() : It is used to compare two pair objects. It does a deep comparison, i.e., it compares on the basic of the values (<Key, Value>) which are stored in the pair objects.
- As usual @girlvsdata You are the savior . Thank you so much... I was just filtering and applying formula each day, had 4 months data. But you saved me AGAIN. Thank you so much...
- @ジョシアヌズ No worries, happy to help. I can't take all the credit for this one, Jeeped did most of the work!
- Thank you so much. It did exactly what I wanted. I was afraid, the data would be same if I changed the day, Like I have logs of 3 months. But it didnt change, I do have newer version of excel too which have MINIFS and MAXIFS. can you also tell me how to do using those formula? But thank you
- Despite the sample data, I believe that the day must be considered a factor and the data may not necessarily be sorted by date/time ascending.
- @Jeeped, correct. I should've disclosed that the formula is based on the assumption that data are chronologically entered from earliest date and time at the top going below.
- @Jeeped It worked with your formula too. But there is 30 days to count of. as you can see 07/01/2018 , it ends until 07/01/2018 . And what I saw is that everytime the table number and bill number is same(no matter which day) ,
checkin timestill takes the time of 1st day. :(
