总结:Using two pointers again, first is to use binary search to find the first target, then make l = mid and r = mid, expand in two directions and break. Then l is the first index, r is the last index. Including the situations that nums.length == 0/1 or only 1 target in arra...

For example, if we have an array with five elements, the index of the last element would be 4: $ my_array=(one two three four five) $ last_element=${my_array[4]} $ echo "The 5th element is: "${last_element}"" The 5th element is: five Copy In this Bash code, we initialized...
ensure that B is the last element of the cell array. If it isn't, move it to the end of A. You cannot assume that B appears at all (in which case return A unchanged), but you can assume B does not appear more than once. So in the example, C = {'MATLAB','HURRAY','SPARKLY...

One of the most frequent operations we perform on an array is removing the last element. There are a few different ways to do this - but one of the most common is to use thepop()method. Consider you have the following array:
peekLast() Method is available in java.lang package. peekLast()方法在java.lang包中可用。 peekLast() Method is used to return the last element of the queue denoted by this deque but without removing the element. peekLast()方法用于返回此双端队列表示的队列的最后一个元素,但不删除该元素。 pee...
