Given a list of daily temperatures T, return a list such 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 of temperatures T = [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 Solution {
public int[] dailyTemperatures(int[] T) {
for(int i=0;i<T.length;i++){
int j=i;
for(;j<T.length;j++){
if(T[i]<T[j]){
T[i]=j-i;
break;
}
}
if(j==T.length) T[i]=0;
}
return T;
}class Solution {
public int[] dailyTemperatures(int[] T) {
int[] result = new int[T.length];
Stack<Integer> stack = new Stack<>();
for (int i = 0; i < T.length; i++) {
while (!stack.empty() && T[stack.peek()] < T[i]) {
ans[stack.peek()] = i - stack.pop();
}
stack.push(i);
}
return result;
