Adding to what Saikat Ghosh has said, the complexity of the solution he presented is O(M+N). Actually you can reduce the complexity to O(MlogM + M). I said reduce (though both are optimal) because N is given to range up to 10^7 but MlogM is of ord... Since your solution is inefficient, it fails for large inputs due to being too slow. Since the number of queries seems to be 2 orders of magnitude smaller than the length of the array (100K vs. 10M in the 3 test cases you posted), it would be more efficient to work just with the queries instead of actually updating the array.

Logic:-This is a very simple problem, here we need to only reverse the array and print the element of the array.As we know that array index starts with zero to n-1. here we just reverse the array by first print the array last index than second last index like n, n-1, n-2,..... up to (greater or equal) 0 (Zero),Note that you don't need to print the actual pairs - you can alter the array to optimize. You should be able to find the maximum element of the array in a single pass (O(n)). Then, for each element, you want to check with how many elements after it it would give a product of less than or equal that amount with. 30 days of code HackerRank solutions.
