О чём код?
//Given a list of daily temperatures, produce a list that, for each day in the input, tells you how many days you would have to wait until a warmer temperature. If there is no future day for which this is possible, put 0 instead. // //For example, given the list temperatures = [73, 74, 75, 71, 69, 72, 76, 73], your output should be [1, 1, 4, 2, 1, 1, 0, 0]. // //Note: The length of temperatures will be in the range [1, 30000]. Each temperature will be an integer in the range [30, 100]. class DailyTemperatures { public int[] dailyTemperatures(int[] temperatures) { int[] result = new int[temperatures.length]; Stack<Integer> stack = new Stack<Integer>(); for(int i = 0; i < temperatures.length; i++) { while(!stack.isEmpty() && temperatures[i] > temperatures[stack.peek()]) { int index = stack.pop(); result[index] = i - index; } stack.push(i); } return result; } }
