thanks for help in advance

@soumilkanwal80 I guess you misplaced the break statement in your code. Instead placing it inside if block, you mistakenly put it outside if block at line no 30. And maximum value could be the last value so run loop till n+1, your’s accepted code with modifications solution link .
