Hello @D19APPND0003
please share correct link.

sorry for the wrong link, new link:- https://ide.codingblocks.com/s/264743

@D19APPND0003
check ur updated code here-> https://ide.codingblocks.com/s/265022

a) on using vector it was giving mle so replaced it with array and declare it as global.

b) when if(k>0 ) then in that case we can simply make value at index i , j same and can call over i+1,j+1.

so made similar changes in that section
