how to approach this problem

Правка en2, от dernier_jour, 2025-03-31 05:24:20

given an array $$$a$$$ of length $$$n$$$, you have to answer $$$m$$$ queries:

  • decrease $$$x$$$ by the numbers greater than $$$x$$$ in the interval $$$[l, r]$$$
  • count the occurrence of $$$x$$$ in the interval $$$[l, r]$$$

i have no progress so far.
