- Select the layer you want to save as jpeg/png, then in the layers panel Photoshop will auto highlight whatever layer is selected.
- Then go to the eye icon beside the selected layer in Layers panel; hold down your alt key and click on the eye.
- This will make only the layer you want to save as jpeg/png visible while hiding other layers.
- Now trim the extra background by going to Image>Trim.
- Save your current image by pressing Alt+Ctrl+Shift+S. It will save your image for web ie. in either png/jpeg format.
source: http://www.algolist.net/Algorithms/Sorting/Quicksort. The divide-and-conquer strategy is used in quicksort. Below the recursion step is described: 1st: Choose a pivot value. We take the value of the middle element as pivot value, but it can be any value(e.g. some people would like to pick the first element and do the exchange in the end) 2nd: Partition. Rearrange elements in such a way, that all elements which are lesser than the pivot go to the left part of the array and all elements greater than the pivot, go to the right part of the array. Values equal to the pivot can stay in any part of the array. Apply quicksort algorithm recursively to the left and the right parts - the previous pivot element excluded! Partition algorithm in detail: There are two indices i and j and at the very beginning of the partition algorithm i points to the first element in the array and j points to the last one. Then algorithm moves i forward, until an element with value greater or equal
