GAT Subject Computer Science MCQs

Recursion solves a problem through smaller self-similar calls and a base case.

Binary search compares with the middle element and halves the remaining range.

A variable associates a name with data that a program can use or change.

A while loop evaluates its condition before each iteration.

An operating system coordinates hardware resources and applications.

Every term is multiplied by 2.
Therefore, 56 × 2 = 112.

An algorithm is an ordered and finite problem-solving procedure.

The successive increases are 3, 4, 5, and 6.
The next increase is 7, so 28 + 7 = 35.

AND produces true only when both operands are true.

The amounts subtracted are 9, 16, and 25, which are 3², 4², and 5².
Subtracting the next square, 6² = 36, gives 50 - 36 = 14.

The terms are factorials: 1!, 2!, 3!, and 4!.
The next term is 5! = 120.

The digit 7 is in the thousands place.
Therefore, its place value is 7 × 1,000 = 7,000.
