- Computer Science Students from CSE, EEE, ETE, ICE, and CE programs take MAT101 course. CSE program has 200 students, EEE program has 100 students, ETE program has 80 students, ICE program has 90 students, CE program has 100 students willing to take MAT101 course. However, due to seat limitation, all students will not be allowed to take MAT101 course. Therefore, students for MAT101 course will be selected at random without looking into their program. Calculate the minimum number of students to be selected for MAT101 course to be sure that at least 13 students are from the same program.arrow_forwardA & B answers are given below please Answer C part Algorithm – We are taking first element of array in A Comparing A with other elements of array, if A is smaller then store that element in A otherwise compare with next element The value of A is the answer A Solution 2000 LXI H 2050 H←20, L←50 2003 MOV C, M C←M 2004 DCR C C←C-01 2005 INX H HL←HL+0001 2006 MOV A, M A←M 2007 INX H HL←HL+0001 2008 CMP M A-M 2009 JNC 200D If Carry Flag=0, goto 200D 200C MOV A, M A←M 200D DCR C C←C-1 200E JNZ 2007 If Zero Flag=0, goto 2007 2011 STA 3050 A→3050 2014 HLT Part (b) Pipeline- The pipeline is the implementation technique where multiple instructions are executed simultaneously.
