  IN second case.. B*O=O {2 possibilities either O=5 or B=6 then only it will give same no.}
  Lets say B=6 then O={2,4,8} but in other cases like 1. if B=6 then B*B should have given result as B {i.e, 6*6=36} but this is not so
  Therefore, O=5;
  Put everywhere O=5
  now B=odd that's why we get O {5* odd= _5 }
  B=3,7,9 ( B~=1 refer case 1)
  put B=3

  M= 1, ?=7,L=6 ,O=5,B=3 (every alpha has distinct values so its correct)

  E=0,Y=9;
  
  so we get..
  M= 1, ?=7,L=6 ,O=5,B=3,E=0,Y=9;

• step 1:check B*0 = O => O = 5
  STEP 2: B = (1,3,5,,7,9)
  this is so that 0 can have its unit digit as 5
  take B values 1 by 1, the correct value will be B = 3
  this will eventually lead to the correct solution
  final result:
