how to approach this problem

Revision en3, by dernier_jour, 2025-03-31 06:11:26

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

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

i have no progress so far.
