Range Array

CodeChefRating 2861Open on judge ↗

Chef has an array $A$ of length $N$. Chef constructs the range-array $A_{L,R}$ as follows: - First, Chef considers the subarray $A_L, A_{L + 1}, . . . , A_{R}$. - Then Chef removes the integers that do not belong to the range $[L, R]$ from the subarray to finally create the range-array $A_{L, R}$. For example, consider the array $A = [1, 3, 2, 4]$, then the range-arrays are: $A_{1, 1} = [1],
