Any changes made in new branch will not affect in other branches. If the file is in the Workspace area then it will be visible to all the branches but once commit to a specific   branch then only those branch can see the file no other can Git branch => to show all the branches Git branch branch-name => creates new branch Git checkout branch-name => shift to given Branch Git merge branch-name => Used to merge the given branch name with the current working branch Git stash => Used to move the current untracked code into local storage avaliblabe stash so that we can work on something else. Then later when something else is done we can take out the unsaved code from stash Git stash list => used to show all the stash avaialbes Git stash apply stash index => used to rollback a specif

Important Question

 Important Question 1. Kadene's Algorithm 2. Sum of largest circullar subarray (Apna college c++ 8.6) 3. Seive of Entjuaists 4. Given an integral number  N . The task is to find the count of digits present in this number. number of digits in N = log 10 (N) + 5. Given a number N, find an integer denoting the smallest number evenly divisible by each number from 1 to n. 6. Rearrange an array so that arr[i] becomes arr[arr[i]] with O(1) extra space 7. Find Peak element in Sorted Array 8. Quick sort 9. Merge sort 10. Minimum swap to short 11. Merge two sorted array in o(1) time --> VVVVIIIMPPP Matrix Questions: rotation of matrix, deternminaent, spiral traversal. search in row and column of sorted matrix(vvvvimp)(apna colllge c++ matrix practive questions) max recatnge(vvvvimp) 12. remainder with 7 vimp 13.   Check if strings are rotations of each other or not   14. convert to roman
