Second problem
245 A[215]
323 A[241]
First problem
190 A[15]

[@kkn2k19]

A[15] will have 180

[@kkn2k19]

since index can't be negative so lowest will be 0th index.

[@official_shamita]

Answers for 1D are: (i) :- 245

arrayindex cannot be negative so how to perform it or what to take the lower bound

[@computershastra]

Lower bound will be given in que... otherwise you may take 0

But when to use row major or column major because ans is one only na

You may use anyone and basic techniques is same... By default when it is not mentioned in question, we take row major

Mam in exam we can do any one method in 2d array??

Yes

Generally, we use row-wise notation

"in array integer require 4 bytes to store data "

[@computershastra]

Is this a question or a statement?

[@abdul_rehman_10]

@@computershastra Question probably ,becuase it takes 4 bytes and not 2 as you described in vid

[@computershastra]

Can you pinpoint question or timeline... in general, integer may take two or four bytes depending upon the compiler

[@shubhiVerma_]

Mam int ka size toh 4 hota h fir 2 kyu use kiya

[@computershastra]

Datatype ka size compiler pe depend krta h.. kuch compiler 2 bytes lete h kuch 4
