You cannot delete apps without losing the associated data. The app space and the data are essentially one.
you can not format a disk without losing the data, so back up all of your data elsewhere before formatting.
Highlight the cells you want to merge by left clicking, holding and dragging until all the cells are identified. At the top of the screen there should be an icon that looks like a square with two arrows pointing left and right; in older versions of Excel the icon says "Merge and Center". Once your cells are highlighted, click on this icon and the cells will merge and any data entered into the merged cell will be centered.
When you merge a cell, the effect produced depends on the way the cells were merged. If it is a parallel connection, the cells functions as a single cell but if it is in series, they will combine their strength.
When copying cells in Excel to a destination where data already exists, you can choose to either replace the existing data with the copied data, keep the existing data and not copy over it, or merge the copied data with the existing data. When moving cells in Excel to a destination where data already exists, the original cells will be replaced by the moved cells.
No, there is not.
yes.
If you merge cells into one cell, the data from the first cell is retained and all other data in the other cells is lost. To get data from lots of cells into another cell you can concatenate them, using the & or the CONCATENATE function. So to combine the contents of cell A1 and B1, to be shown in C1, you could do this: =CONCATENATE(A1,B1) or =A1&B1 To put a space between the contents of the two cells then you would change it slightly, like these: =CONCATENATE(A1," ",B1) =A1&" "&B1

You can try that with some tools but if you have lost some important data then I'll suggest you to visit an expert for your HDD data recovery.
Merge sort is good for large data sets, while insertion sort is good for small data sets.
