Ans. 
Find minimum cost to reach end of array by jumping with constraints
• Use dynamic programming to keep track of minimum cost at each index

• Iterate through the array and update the minimum cost based on reachable indices within K steps

• Calculate cost to jump from current index to reachable indices and update minimum cost accordingly

Out...read more
Ans. 
The maximum sum of any contiguous subarray in an array is found using Kadane's algorithm in O(N) time.
• Initialize two variables, maxSum and currentSum, both set to the first element of the array.

• Iterate through the array from the second element.

• For each element, update currentSum by adding the element to it.

• If currentSum becomes negative, reset it to 0.

• If currentSum is greater than maxSum, update maxSum.

• After iterating ...read more
