sir in this question 5 4 3 3 4 5 6 this also should be a valid order isnt it as this can be broken down into two sub-arrays
Array1->5 4 3
Array2->3 4 5 6
as Array1 is strictly decreasing and array2 is strictly increasing isnt it???
Increasing decreasing order
@tejasddongare according to the question it should be but i think test cases consider it as false. just try doing both no worry
dont forget to hit like and mark resolved if cleared
