+description: The "Plus One" dsa problem is a classic algorithm challenge that involves manipulating an array of digits. The goal is to add one to a number represented by an array of its digits.

+# Plus One
+
+## Description
+You are given a large integer represented as an integer array ``digits``, where each ``digits[i]`` is the ``ith`` digit of the integer. The digits are ordered from most significant to least significant in left-to-right order. The large integer does not contain any leading ``0``'s.
+Increment the large integer by one and return the resulting array of digits.
+
+### Example 1:
+
+**Input:** digits = [1,2,3]
+
+**Output:** [1,2,4]
+
+**Explanation:** The array represents the integer 123.
+
+Incrementing by one gives 123 + 1 = 124.
+
+Thus, the result should be [1,2,4].
+
+### Example 2:
+
+**Input:** digits = [4,3,2,1]
+
+**Output:** [4,3,2,2]
+
+**Explanation:** The array represents the integer 4321.
+
+Incrementing by one gives 4321 + 1 = 4322.
+
+Thus, the result should be [4,3,2,2].
+
+### Example 3:
+
+**Input:** digits = [9]
+
+**Output:** [1,0]
+
+**Explanation:** The array represents the integer 9.
+
+Incrementing by one gives 9 + 1 = 10.
+
+Thus, the result should be [1,0].
+
+# Code in Java
+
+```java
+class Solution {
+    public int[] plusOne(int[] digits) {
+        int n = digits.length;
+
+        for(int i=n-1; i>=0; --i) {
+            ++digits[i];
+            digits[i] = digits[i] % 10;
+            if(digits[i] != 0) {
+                return digits;
+            }
+        }
+        digits = new int[n+1];
+        digits[0] = 1;
+        return digits;
+    }
+}
+```

+description: The "Find Indices of Stable Mountains" problem on involves identifying mountains that meet a specific stability criterion 1.

+
+# Find Indices of Stable Mountains
+
+## Description
+There are ``n`` mountains in a row, and each mountain has a height. You are given an integer array ``height`` where ``height[i]`` represents the height of mountain ``i``, and an integer ``threshold``.
+
+A mountain is called stable if the mountain just before it (if it exists) has a height strictly greater than ``threshold``. Note that mountain 0 is not stable.
+
+Return an array containing the indices of all stable mountains in any order.
+
+### Example 1:
+
+**Input:** height = [1,2,3,4,5], threshold = 2
+
+**Output:** [3,4]
+
+**Explanation:**
+
+Mountain 3 is stable because height[2] == 3 is greater than threshold == 2.
+Mountain 4 is stable because height[3] == 4 is greater than threshold == 2.
+
+### Example 2:
+
+**Input:** height = [10,1,10,1,10], threshold = 3
+
+**Output:** [1,3]
+
+### Example 3:
+
+**Input:** height = [10,1,10,1,10], threshold = 10
+
+**Output:** [ ]
+
+## Approach
+
+**1. Iterate Through Mountains:** Loop through the array starting from the second mountain.
+
+**2. Check Stability:** Compare the height of the current mountain with the height of the previous mountain.
+
+**3. Collect Stable Indices:** If the previous mountain's height is greater than the threshold, add the current mountain's index to the result list.
+
+# Code in Java
+
+```java
+class Solution {
+    public List<Integer> stableMountains(int[] height, int threshold) {
+        List<Integer> stableMountains = new ArrayList<>();
+        for(int i=1; i<height.length; i++) {
+            if(height[i-1]>threshold) {
+                stableMountains.add(i);
+            }
+        }
+        return stableMountains;
+    }
+}
+```
