+# Day 23
+
+Today we will learn to go back on where we were before.
+
+## Problem Statement:
+Say you were looking at something in the past, and then switched back to the main branch.
+
+But then, you got really distracted, and after your lunch break, you can't remember on which commit in the past you were before. How can you find out?
+
+There's a convenient command that shows you all the places your
+HEAD did point to in the past:
+`git reflog`
+
+### Question:
+ - Find out where you've been before, and go back there!

+
+## Solution:
+
+1. Use the reflog command to find out the pattern.
+```bash
+git reflog
+```
+The output of the above command comes out to.
+```term
+726971f (HEAD -> main, 10) HEAD@{0}: checkout: moving from 3 to main
+151f810 (3) HEAD@{1}: checkout: moving from main to 3
+726971f (HEAD -> main, 10) HEAD@{2}: commit: 10
+06a8ddd (9) HEAD@{3}: commit: 9
+4a9b680 (8) HEAD@{4}: commit: 8
+0236645 (7) HEAD@{5}: commit: 7
+b5a3437 (6) HEAD@{6}: commit: 6
+7df3b91 (5) HEAD@{7}: commit: 5
+1113cb6 (4) HEAD@{8}: commit: 4
+151f810 (3) HEAD@{9}: commit: 3
+97c719a (2) HEAD@{10}: commit: 2
+374d0a3 (1) HEAD@{11}: commit (initial): 1
+```
+
+2. From the output, you found that we need to go to the 3rd branch.
+```bash
+git checkout 3
+```
