Hello @Nidhi_Alipuria,

Please, share your code on Online Coding Blocks.
The way you have shared may introduced many syntax errors to it.
Steps:

  1. Paste your code at https://ide.codingblocks.com/.
  2. Save it there.
  3. Share the URL generated.

prefix_array[BRi][TLj-1], prefix_array[TLi-1][BRj], prefix_array[TLi-1][TLj-1] will cause issue for the case when either TLj, TLi or both are 0.

Correct your code for this.

Hope, this would help.
Give a like if you are satisfied.
