Given an array arr[], the task is to find all the maximal contiguous increasing subarray in a given array.
Examples:
Input:
arr[] = { 80, 50, 60, 70, 40, 50, 80, 70 }
Output:
80
50 60 70
40 50 80
70Input:
arr[] = { 10, 20, 23, 12, 5, 4, 61, 67, 87, 9 }
Output:
10 20 23
12
5
4 61 67 87
9
Approach: Iterate over the array and compare every element with its next neighboring element such that, if it is less than the next element, print it, else print it individually on the next line.
Below is the implementation of the above approach.
// C++ Implementation to print all the // Maximal Increasing Sub-array of array #include <bits/stdc++.h> using namespace std;
// Function to print each of maximal // contiguous increasing subarray void printmaxSubseq( int arr[], int n)
{ int i;
// Loop to iterate through the array and print
// the maximal contiguous increasing subarray.
for (i = 0; i < n; i++) {
// Condition to check whether the element at i, is
// greater than its next neighbouring element or not.
if (arr[i] < arr[i + 1])
cout << arr[i] << " " ;
else
cout << arr[i] << "\n" ;
}
} // Driver function int main()
{ int arr[] = { 9, 8, 11, 13, 10, 15, 14, 16, 20, 5 };
int n = sizeof (arr) / sizeof (arr[0]);
printmaxSubseq(arr, n);
return 0;

Time Complexity: O(n)
Auxiliary Space: O(1), no extra space is required, so it is a constant.
